  • Transmit Antenna Selection Strategies for SC- FDMA- IDMA Massive MIMO
           Systems

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  Roopali Agarwal   and M. Shukla   The 5 G wireless offers many advancements over the prevalent 4 G LTE communication networks, such as enhanced data transmission rates (in order of Gbps), Substantially reduced latency, many times increase in the Base Station Capacity and praiseworthy betterments in the QoS offered to the users. IDMA has already proven its potential in 5 G and it can be easily integrated in to massive MIMO systems. The ideology behind the concept of Massive MIMO is to match the requirement for efficient usage of spectrum, and is implemented using several numbers of antennas at the Base Station, catering to a number of subscribers concurrently using same band of the given frequency. However, the cost and complexity of implementation of such large-scale antenna systems is quite high. Thus for reduction in the number of radio frequency chains, the technique of Transmit Antenna Selection is used. In this paper, we propose two transmit antenna selection strategies considered for individual user or overall users based on selection criteria maximum sum rate or minimum bit error performance considering for (MIMO) multiuser multiple input and multiple output single carrier frequency division multiple access based interleave division multiple access wireless system (MIMO-SCFDMA-IDMA). We have taken this scheme for the uplink communication and selection of the subcarrier is through the bulk selection. The performance may get degraded in case of heavy load of multiple subcarriers attached to one antenna, which will in turn call for the role of power amplifier and thus efficiency of the system may go down. Therefore, here we prefer bulk subcarrier selection instead of per subcarrier selection. It is shown in this paper that enhanced sum rate can be achieved as more users are allowed to transmit concurrently, and thus multiuser gain is achieved. We also demonstrated the comparison with simulation result of sum rate performance and Bit error rate performance of varying users. Result shows that antenna selection based on overall system is better than the antenna selection considering each user.

  • New Method for Assessing the Energy Potential of Wind Sites - A Case Study
           in Jordan

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  Ayman Al-Quraan   Hussein Al-Masri   and Ashraf Radaideh   This paper presents a technical assessment of wind power potential for five promising wind sites in Jordan: Tafila, Zabda, Royal Scientific Society, Al-Alia and Al-Reesha wind sites. This assessment is based on developing a new methodology of estimating the wind energy by estimating the main wind parameters for a specific wind site. The developed methodology is originally based on a website data provided by the national wind energy atlas. Microsoft excel environment is used to estimate the total wind energy, the maximum repetition wind speed and the wind speed contributing the maximum energy in a specific wind regime. The validation process for this methodology has been carried out using measured wind speed data provided by the Energy Research Centre. The error between the estimated wind energy and the measured value is less than 10% for all cases. The highest energy is available in Tafilah wind site with around 6 MWh. In order to obtain an accurate comparison for the selected sites, the wind energy was estimated at uniform height, selected to be the standard height (10m). The importance of this model is that it can be utilized routinely to assess the wind energy potential in a specific location, so a decision can be made whether a wind farm can be built or not in that location without any need to install anemometers.

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  K. Pranitha   G. Kavya   and M. Arun Kumar   This paper aims to provide consolidated procedure to design and implement VLSI block in Arty A7 kit using VIVADO HLS. Sine wave signal with appropriate pulse width is implemented and default hardware part is selected in VIVADO HLS tool and verilog code has been written in VIVADO IDE for the implementation of Arty A7 kit. Using high level synthesis, an engineer has the contingency to add libraries for the corresponding project and further proceeds with the achievement at superior level of entrancement. The procedure of implementing sinusoidal signal and the performance of implementation in Arty A7 kit using vivado HLS is illustrated along with simulation, synthesis, implementation results and project summary report. Timings, Design rule check (DRC) violations, utilization, total on-chip power are charted in project summary report. The proposed research work is based on FPGA implementation based image compression/decompression using VIVADO HLS. Proposed work is widely used in medical application especially in telehealth where patient records are transferred from remote area to the hospital to make consultation in easier manner. Likewise FPGA implementation based image compression/ decompression is used in fields like remote sensing, oceanography, earth observation etc. to predict the future weather conditions and it helps to take precautionary steps in order to detect the disaster before it occurs. Initial proposed research work has been done based on FPGA implementation of sinusoidal signal using VIVADO HLS. Future research work, FPGA implementation based image compression/decompression will be carried out using VIVADO HLS. The main advantage of Vivado HLS tool is to obtain high speed performance and low power consumption while implementing in hardware.

  • Three-Level Laser Coupled to Squeezed Vacuum Reservoir

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  Menisha Alemu   We analyze the quantum properties of the light generated by a three-level laser with an open cavity and coupled to a two-mode squeezed vacuum reservoir via a single-port mirror. The three-level laser consists of three-level atoms available in an open cavity and pumped from the bottom to the top level by means of electron bombardment. Applying the large-time approximation scheme, we have obtained the steady-state solutions of the equations of evolution for the expectation values of the atomic operators and the quantum Langevin equations for the cavity mode operators. Using the resulting steady-state solutions, we have calculated the mean photon number, the variance of the photon number, and the quadrature variance for the two-mode cavity light. We have seen that the light generated by the three-level laser is in a squeezed state and the squeezing occurs in the plus quadrature. It so turns out that the maximum quadrature squeezing of the two-mode cavity light is 45:68% for M0 = 0:59 and N0 = 0:27 below the vacuum-state level. In addition, we have shown that the effect of the squeezed parameter is to increase the mean and variance of the photon number.

  • Backstepping Control of Rewinding Systems with Flexible Couplings

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  Thi Ly Tong   Hiep Binh Nguyen   Duc Thanh Cao   and Tung Lam Nguyen   Roll-to-roll (R2R) system can be found and applied in various fields, such as paper manufacture and printing process. The matter regarding tension control is still a challenge because this tends to rely on elasticity of web materials with its elasticity and roll inertia which change. Additionally, another issue is limited stiffness shafts connecting the web handling system and driving motor. Due to non-rigid nature of the shafts, un-wanted vibration can be released, and this impact to the system. Therefore, the tension control is more complicated. In this paper, a control solution for a roll-to-roll web-transport system with flexible couplings will be performed. The connection of this system coupled with motors through non-rigid driving shaft is formed as a two-mass system. Moreover, the paper shows that the thickness of web material is assumed to be conscious in order to achieve a simple calculation of roll inertia momentum. By using backstepping control technique, control laws for unwinding and rewinding roll are defined. The control schemes ensure a linear velocity and tension tracking performance of the system. Extensive numerical simulations are carried out to verify the feasibility of the proposed control strategy. The simulation results indicate the effectiveness of the proposed control, web tension and position are driven to desired values.

  • Trends and Challenges in Grid-Tied Inverters for Photovoltaic Applications

    • Abstract: Publication date:  Jun 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  3  Geetha K   and Sreenivasappa B V   Grid-Tied inverter has gained the attention of many researchers and power generation industry due to its capability of integrating distributed power generation systems using renewable energy resources with the existing centralized power generation system. Yet the inclusion of a transformer in the Photovoltaic (PV) inverter makes it bulkier, heavier and more expensive. A primary solution to the aforementioned problems is the transformerless PV Grid-Tied inverter. This paper presents a review of different transformerless, single-phase Grid-Tied inverter topologies. The objective of this paper is to study parameters such as leakage current, common-mode voltage, total harmonic distortion, and the efficiency of transformerless Grid-Tied inverters. The paper also provides a discussion on existing Grid-Tied inverter topologies, such as H5, oH5, Novel H5, H5-D, FBDC, H6D2, Hybrid H6, High-efficiency MOSFET H6, Improved H6, 3L H6, H6-A, B, High-Efficiency H6, H6-N, Improved H6, H6-active clamping, Active clamped snubber based H6, Heric, oHeric, Enhanced Heric, Heric-with mid-DC-link, Active clamping, PN-NPC, Improved FBNPC, T-Type 3L, ANPC, HBNPC, NIFB-NPCI, VNIIFBC, M-NPC, Virtual DC bus based inverter, Active Virtual Ground, Type I, Type II, Type III Common Ground, Flying Capacitor and Multilevel Common Ground. Though it is found that many topologies available in the literature, other new topologies can be proposed to improve the performance of the inverter. Furthermore, it is also noted that the performance analysis of the inverter must be carried out in the presence of junction capacitance and shoot-through problem so that new strategies can be introduced in the existing typologies to address these issues.

  • Performance Investigation of Quasi Z Source Inverter (QZSI) Fed Induction
           Motor (IM) Drive System with bGWO-RDF Technique

    • Abstract: Publication date:  Feb 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  1  Shunmugakani P   and D. Kirubakaran   In this dissertation, a hybrid strategy is intended for performance investigation of Quasi Z Source Inverter (QZSI) fed Induction motor (IM) drive system. The hybrid strategy is the fusion of both the binary version of grey wolf optimization (bGWO) and random decision forest (RDF) and commonly called as bGWO-RDF technique. The main contribution of the dissertation is to control the QZSI for enhancing the stability and the performance of IM drive system using the proposed hybrid strategy. The input of the proposed strategy is the speed and three phase current of IM. With the help of input parameters like actual speed and reference speed of IM, the PI controller gain parameters are optimized using bGWO technique. In order to train the RDF, the PI controller output like reference quadrature axis current and actual quadrature axis current is chosen. By utilizing the RDF, the reference three phase current is generated. By utilizing the actual and reference three phase current, the control pulses are generated at the final stage. Finally, the proposed technique is executed in the MATLAB/Simulink working platform. The effectiveness of the proposed is compared with various existing techniques such as ANN, PSO, PSO-SVM and GSA-SVM. The effectiveness of the proposed and other existing techniques is analyzed in terms of ripples and harmonics reduction, rise time, settling time and steady state error. Furthermore, the statistical analysis is also performed and compared with other existing techniques. The comparison result reveals that the total harmonic distortion (THD) is decreased and the oscillation period of the stator current, torque and speed are eliminated.

  • Simulation and Experimental Investigation of Modulation Techniques for
           BLDC Motor Control

    • Abstract: Publication date:  Feb 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  1  Ivan Maradzhiev   Tsvetana Grigorova   and Emil Dinkov   The following paper investigates and analyses the electromagnetic processes in an electrical drive system composed of a power source, a power inverter and a brushless dc (BLDC) motor using known pulse-width modulation (PWM) methods. Investigated modulation techniques are: unipolar modulation of the upper transistors (PWM-TOP) and bottom transistors (PWM-BOT), symmetrical PWM-PWM, modulation type PWM-ON and ON-PWM, and bipolar PWM-ON modulation indicated with PWM-ON-BIP. The voltage source inverter is considered as DC-DC buck power converter, when BLDC is operated in motor mode. On the basis of summarized equivalent circuits, the analytical expressions are received for the electromagnetic processes in the system by the different modulation techniques. The efficiency of the system battery-inverter-machine for each discussed modulation is experimentally investigated and compared. These results are also compared with the efficiency of the BLDC driven with vector control. A MATLAB/SIMULINK model is proposed to implement these modulations and to analyze the obtained results. From this model, the harmonic composition of the phase currents for each modulation is investigated.

  • MATLAB-Based GPU Acceleration for Multiple-Input and Multiple-Output Radar
           Beamforming Algorithm

    • Abstract: Publication date:  Feb 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  1  Mostafa Hefnawi   and Gillian Rideout   Multi-input and multi-output (MIMO) radar systems possess numerous advantages, such as scanning an entire region much faster than a phased array, enhancing the spatial resolution, mitigating interference and multipath fading, and improving the probability of detection of targets. MIMO radar systems use adaptive beamforming techniques such as the minimum variance distortionless response (MVDR) to obtain the best possible estimation of the direction of arrival (DOA) of the targets. The MVDR algorithm has been thoroughly investigated for traditional phased array radars. For MIMO radar systems, however, it requires significant signal processing, which can introduce substantial latency, especially in the case of large MIMO systems where few hundred antennas are used; this can be solved by using a Graphics Processor Unit (GPU), which contains thousands of cores and can execute many operations in parallel. This paper presents a MATLAB-based approach for GPU parallelization of the minimum variance distortionless (MVDR) beamforming algorithm in a MIMO radar system. Two MIMO radar systems are considered. The first one is a simulated MIMO radar which is used for automotive adaptive cruise control (ACC), and the second one is an experimental monostatic MIMO radar that is based on a vector network analyzer (VNA). It is shown that the GPU achieved a speedup of up to 7 times while successfully detecting all targets.

Allowing electric vehicles to charge/discharge without any control technique may lead to variations of the voltage & disturbances to the utility grid, but when the charging/discharging of the electric vehicles is achieved in a smart way, they can support the power grid. In this work, fuzzy techniques are applied to control the power flow among the grid and the EVs. The work introduced in this paper mainly concentrates on the control technique for a V2G system which allows for using electric vehicles batteries to assist the grid voltage stability. The designed controllers maintain the node voltage and achieve peak power. The proposed controllers are tested on (16&6) generator test systems to check the performance of the suggested designs. Two fuzzy schemes are examined to explain the vehicle to grid ability to impact system voltage stability. The main contributions of this paper, fuzzy technique based control tool for vehicle to grid illustrate at a weak bus in the system and comparison of chargers producing active vs. reactive powers.

  • Translating Hierarchical Simulink Applications to Real-time multi-core
           Execution

    • Abstract: Publication date:  Aug 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  4  Asma Rebaya   Karol Desnos   and Salem Hasnaoui   Matlab & Simulink is is widely used as a defacto standard to design industrial applications, video coding & decoding, and signal processing applications. However, with the spectacular increase in the number of the cores available in hardware platforms over these last years, passing from Simulink to multi-core execution becomes more and more complex. In this context, several researches are done to take benefit from the high degree of parallelism and to perform multi-core programming of Simulink applications. In this paper, we present an automated method for transforming hierarchical Simulink applications to embedded parallel software implementation. Our method consists of using IBSDF (Interfaced based Synchronous Dataflow) as an intermediate representation to extract parallelism. Moreover, our approach permits preserving synchronous semantics and hierarchical behavior of the Simulink model. The model-based approach makes it possible to verify the key properties of the system at compile-time, such as deadlock freeness and memory boundedness. The method has been implemented as an extension of the rapid prototyping tool named Preesm. Experiments show that our proposal gives, as a transformation result, a schedulable IBSDF graph equivalent in size to the Simulink model and allows better multi-core implementation performance than Matlab & Simulink sequential execution.

  • Maximizing the Lifetime of Wireless Devices in Millimeter Wave UAV
           Networks

    • Abstract: Publication date:  Aug 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  4  Hazim Shakhatreh   and Waed Malkawi   The use of unmanned aerial vehicles (UAVs) is growing rapidly across many civil application domains, including providing wireless coverage. Most studies on UAV-based wireless coverage typically consider downlink scenarios from an aerial base station to ground users. The uplink scenario in which ground wireless devices transmit data to an aerial base station is only considered by few studies. However, the frequency bands that are used in these studies are not Millimeter Wave frequency bands, and this limits the applicability of these applications when one needs to consider 5G networks. In this paper, we are motivated to explore if the placement of UAV can enhance the time durations of uplink transmissions of wireless devices in Millimeter Wave UAV networks. First, we present a realistic Millimeter Wave path loss model and describe the tradeoff introduced by this model. Then, we study the problem of optimal UAV placement, where the objective is to determine the placement of a single UAV such that the sum of time durations of uplink transmissions is maximized. To this end, an algorithm to find the optimal UAV location is proposed. Simulation results are presented to validate the effectiveness of the proposed algorithm.

  • Zinc Sulfide Waveguide Analysis

    • Abstract: Publication date:  Aug 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  4  Abd-Alrahman Khalid   and Nabeil I. Fawaz   The Maxwell equations are considered as fundamental formulation of wave propagation for a dielectric slab waveguide at frequencies in the IR region. In this article, the theoretical analysis of electromagnetic waves propagating through the zinc sulfide (ZnS) semiconductor planar waveguide at wavelength of 1 µm is reported using 2013 MATLAB software. Additionally, a comparison of the waveguide parameters using two modes namely transvers electric (TE) and transvers magnetic (TM) is demonstrated in details. This could be attributed to the interference of effective refractive index value. In particular, the penetration depth has demonstrated values of 0.2419 and 0.2445 µm for TE0 and TM0 modes at thickness of 2.69 µm, respectively. Subsequently, the effect of temperature on the effective reflective index has been elaborated. Furthermore, the propagation angles in TM modes exhibited lower values than TE modes with respect to the core thickness; and lower wavelength resulted in higher cutoff frequency with respect to the number of modes. While, the relation between neff and temperature for both TE and TM modes showed that TE mode exhibited advanced values as compared to TM mode. This work demonstrates a short pathway for a theoretical analysis of electromagnetic waves through ZnS planer waveguide using both TE and TM modes.

  • Ground Moving Target Imaging (GMTIm) Algorithm in OFDM SAR Based on
           First-Order Keystone Transform

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Mohammad Zeighami   Mohammad Hassan Bastani   and Fereidoun Behnia   The use of Orthogonal Frequency Division Multiplexing (OFDM) waveform in place of Linear Frequency Modulation (LFM) signal is one of the latest topics in the field of Synthetic Aperture Radar (SAR) imaging. The advantages of imaging by this technique include resistance to certain types of radar jamming techniques, reduced ambiguity in Doppler spectrum with an increase in the number of sub-bands, and extraction of target phase history based on phase approximation of all OFDM subcarriers. In conventional SAR imaging algorithms, it is assumed that the targets are stationary in the imaging zone as these algorithms do not have the required efficiency to image moving targets, leading to blurred images and high Integrated Side Lobe Ratio (ISLR). To circumvent these problems, there is a requirement of designing appropriate imaging algorithms, keeping in mind the important issues related to the moving targets in the imaging zone. Thus, in this study, we propose the implementation of the OFDM waveform for imaging moving targets alongside the first-order keystone transform to solve the above-mentioned problems.

  • Performance Study and Synthesis of the New LDPC Error Correcting Code
           Using the Bit-Flipping Algorithm

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Lagrini Lakbir   El Habti Idrissi Anas   and Moulay Brahim Sedra   The discovery in 1993 of the turbo codes Berrou C., A. and P. Glavieux Thitimajshima at the International Conférence of Communication Florida has revolutionized communication. This innovation made it possible to rediscovery the error correcting codes invented by Robert Gallager in 1963 and rediscovered by Mackay in 1995, currently called Low Density Parity Check (LDPC). This code is one of the error correction codes introduced by the transmission channel that have the fastest and most effective level of protection and correction of the information transmitted during the communication. This code has been almost generalized in communication standards such as satellites. The objective of our article is to minimize the number of iterations and in some cases completely remove the iteration produced by the LDPC code bit flipping algorithm. The result of this algorithm, if we take for example the LDPC code (n, k), the number of possible syndromes which we can find is 2k-1 and for each syndrome different from zero, we can do almost four iterations to correct the errors, which gives 4x(2k-1) iterations in totality. On the other hand, the proposed algorithm removes the iteration for k syndromes and reduces iterations for the rest of the cases from four to two iterations. This study of the new design gave more performance results and the results of the simulation below according to a hardware description language used in digital electronics using quartus software tools show the importance of this algorithm.

  • PCA Data Reduction for MIMO Based Channel, Capacity Enhancement Using
           16-QAM Modulation

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Panem Charan Arur   Deepak Chodankar   Rajendra S. Gad   and G. M. Naik   In the Modern Wireless Communication Systems, there is a direct need for the enhancement of the network capacity, in order to support more and more data. This paper describes the data reduction methodology for enhancement of channel capacity based on Principal Component Analysis (PCA) of the Multiple-Input-Multiple-Output (MIMO) based untether communication system. The communication system has employed 16 Quadrature Amplitude Modulation (16-QAM) scheme with LDPC for channel coding method for error correction. The proposed method here utilizes the Principal Component Analysis (PCA) for data reduction which transmits only the feature vectors i.e. Eigen Vector for the set of composite data for large numbers of signals data over time-stamped. The effectiveness of the proposed work is evident through the simulation results of the systems incorporating 1×1, 2×2, 3×3, 4×4 MIMO networks. We have presented RMSE analysis for the PCA regression for verification of the signal fidelity and the BER for confirmation of the recovery of the data over MIMO channel over LDPC coding. Here we observe that our proposed work has achieved much better results.

  • Nonvolatile Memory Cell Based on Memristor

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Santosh Parajuli   Ram Kaji Budhathoki   and Hyongsuk Kim   Memristor, one of the fundamental circuit elements, has promising applications in non-volatile memory and storage technology as it can theoretically achieve infinite states. Information can be stored independently in these states and retrieved whenever required. In this paper, we have proposed a non volatile memory cell based on memristor emulator. The circuit is able to perform read and write operations. In this memristor based memroy cell, unipolar pulse is used for writing and bipolar pulse is used for reading. Unlike other earlier designs, the circuit does not need external read/write enable switches to switch between read and write operations; the switching is achieved by the zero average bipolar read pulse given after the completion of write cycle. In our proposed memristor based memory cell, single bit can be read and any voltages from 0 to 5 volts can be written. Mathematical analysis and the simulation results of memristor emulator based read write circuit have been presented to confirm its operation.

  • Cepstrum Multitaper Method for Optimal Detection of Cognitive Radio
           Networks

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Hebat Allah O. Selim   and Waheed Sabry   Multitaper method (MTM) is an unpopular method that used for spectrum detection. MTM is a good candidate to detect spectrum holes in cognitive radio networks. MTM is accurate, efficient and reliable technique. Cepstrum MTM is described as an effective tool for variance reduction beside its ability in increasing spectrum dynamic range (SDR) due to its isolation property which can be applied to the multiplied mixed signals. As a matter of fact, introducing cepstrum with MTM has achieved better detection performance with the available constraints. In this paper, an algorithm is prepared as a cepstrum MTM for optimal detection and applied to cognitive radio networks. Simple and computationally efficient mathematical expressions of the mean and variance were derived. A closed form expression for the probability of detection (Pd) and false detection (Pf) were obtained accordingly. Analysis of the suggested MTM based cepstrum detection is provided. Different aspects of spectrum sensing parameters were considered in the simulation. A receiver operating characteristic curve is tested where there is a relation between Pd and Pf. The required sample size to achieve certain detection, and the relation of Pd versus signal to noise ratio were also verified. Simulation results were obtained under different affecting factors of the proposed scheme such as probability of false alarm, number of sample points (N), and number of tapers (K). Simulation results reveal that the proposed detector outperforms conventional available tools at the worst scenario operating conditions. The proposed scheme outperforms convention MTM and energy detection by 20% and 45% respectively.

  • Structural-Parametric Synthesis of an Adaptive Fuzzy-Logical System

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Siddikov Isamiddin Xakimovich   Umurzakova Dilnoza Maxamadjonovna   and Yadgarova Dilnoza Baxtiyarovna   One of the ways to improve the quality of the process of managing dynamic objects, in the presence of various types of uncertainty of external and internal factors, due to insufficient information about the object and useful signals and noise acting on it, is to develop new and improve existing methods and algorithms for solving problems of structurally parametric synthesis of neuro-fuzzy control systems that can significantly expand the capabilities of dynamic systems. An analysis of existing approaches showed that at present, traditional methods of controlling the absorption process do not meet modern requirements, due to the lack of a system analysis of the entire set of control systems as a whole, the structure of the system and the relationship between its functional elements, etc. The aim of the work is to create an automatic control system dynamic object, allowing to overcome the difficulties associated with the non-stationary process, structural and parametric uncertainty and variability of external influences. A technique for the synthesis of a high-speed control algorithm based on fuzzy-logical inference is proposed, which allows to eliminate empty and zero solutions when determining the architecture and calculating the weights of arcs of a neural network. To correct the parameters and structure of the fuzzy-logical controller, an adaptation block is proposed in the control system loop. The originality of the proposed synthesis method is to ensure high speed of finding control actions due to the possibility of eliminating the redundancy of computational procedures associated with discarding empty and zero solutions in the formation of control devices when choosing the architecture of a neural network and calculating synapse weights. The proposed structural-parametric adaptation algorithm in the process control problems allows to reduce the number of iterations in the process of network training, to reduce the error in the calculation of control values 8 to 1%.

  • Investigation of Power Losses by Various Brushless Motor Modulation
           Methods in Motor Mode

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Ivan Maradzhiev   Tsvetana Grigorova   and Emil Dinkov   The paper presents a comparative analysis of different modulation techniques for BLDC motor control in terms of several types of losses in the system inverter – BLDC motor in motor mode. The experimental investigated modulation strategies are: unipolar modulation of upper (PWM-TOP or UT) transistors, a bipolar PWM-ON modulation (PWM-ON-BIP), a symmetrical modulation (PWM-PWM), a vector control and non-modulation mode. A simple equivalent circuit for the BLDC motor is used to calculate different losses and the system efficiency. On the basis of the equivalent circuit for the different modulation techniques, simple design procedures are discussed for the determination the eddy current and mechanical viscous loss, the copper loss, the hysteresis and mechanical friction loss, the voltage-drop loss of the inverter transistor and diode. Loss distribution experimental data for the brushless DT4260 motor when operating with different modulations and load torque are presented. On the basis of the obtained values for the efficiency of the studied modulations, references for use in battery powered devices such as electric vehicles, electric scooters and more are made.

  • A Combined WU-shaped NRI Metamaterial for Dual Band Microwave Application

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Krishnan Sinha   Sikder Sunbeam Islam   and Mohammad Jakir Hossain   In the field of electromagnetism, artificially constructed metamaterial has opened a new hope for the researchers. Metamaterial is developed artificially and not found available in nature. This composite material shows more irregular properties than the natural materials. Negative refractive index (NRI) is one of the exceptional properties of it. Therefore, many researchers have started investigation with this material. Some metamaterials found in literature have NRI properties but very few of them are found operating simultaneously in C-and X-band. In this study, a new combined WU-shaped NRI metamaterial unit cell is presented. Here, three different substrate materials have been adopted for sensitivity analysis. The used substrate materials are FR-4, Rogers RT6006 and Rogers RT6010 and their permittivity are 4.3, 6.15 and 10.2 respectively. Finite integration technique based numerical tool is adopted for all analyses. The electromagnetic properties are determined by Nicolson-Ross-Weir (NRW) method. Perfect electric-magnetic boundary condition is applied for simulation. The metamaterial unit cell exhibits negative refractive index (NRI) within C-band and X-band for all these substrate materials. C-and X-band are widely used for satellite and long distance communication. Moreover, the proposed material shows better effective medium ratio with increasing relative permittivity which ensures the materials proper operation and sensitivity for any applications.

  • Improvement of the PSO Algorithm to Solve the Nonlinear Economic Dispatch
           Problem with a New Local Search Algorithm

    • Abstract: Publication date:  Apr 2020
      Source:Universal Journal of Electrical and Electronic Engineering  Volume  7  Number  2  Mohammad Reza Gholami Dehbalaee   Gholam Hossein Shayci   and Majid Valizadeh   This paper suggests a new PSOHHC algorithm for solving the economic dispatch (ED). This algorithm was created by integrating two algorithms: PSO (particle swarm optimization) algorithm, an evolutionary algorithm based on collective intelligence, and a new search algorithm for HHC (Hybrid Hill Climbing) which is based on searching. The aim of presenting this algorithm is to improve the performance of the PSO algorithm in terms of convergence to achieve the best possible solution with the required accuracy. This new algorithm is able to improve the responses obtained from the PSO algorithm with a controllable local search. The most important goal of economic dispatch is the optimal allocation of each generator's contribution to provide the load and reduce the costs of active units in the power system. This is generally due to the nonlinear factors and limitations, such as: the effect of steam inlet valve (valve point effect (VPE)), the balance between the production and consumption of the system, the prohibited operating zones (POZS), production limits, slope rate, and lines' losses. This algorithm is implemented on 3 test systems of 13 units, 31 units and 40 units with different operating conditions, independently and also in combination with the PSO evolutionary algorithm, and simulation results illustrate the efficiency of this algorithm in solving ED problems.
