  • An adaptive approach for the fault tolerant control of a nonlinear system
    • Authors: K. Sudha, V. Thulasi Bai
      Pages: 105 - 123
      Abstract: In this paper hybridisation between two optimisation methods such as modified bacterial foraging optimisation algorithm (MBFOA) and adaptive neuro fuzzy inference system (ANFIS) is presented for determining the optimal proportional-integral (PI) controller parameters, for fault tolerant control (FTC) in an wind energy conversion system (WECS). Initially, detection and diagnosis of fault is performed by the ANFIS. The wind turbine actual output performance and the estimated output values are given as an input to the ANFIS. The residuals, which are the outputs of ANFIS is used for deciding, whether the signal is a fault signal or a non-fault signal, which utilises the knowledge-based computation technique. By using the step size modified bacterial foraging optimisation algorithm-based FTC, the gain parameters are optimised based on the occurrence of fault. Then the proposed hybrid fault tolerant control model is implemented in the MATLAB/SIMULINK platform and the effectiveness is analysed by comparing with the other techniques. The comparison results demonstrate the superiority of the proposed approach and confirm its potential in controlling the fault in a WECS.

  • Comparison of identification techniques of fractional differential
           equations
    • Authors: Abir Khadhraoui, Khaled Jelassi
      Pages: 124 - 142
      Abstract: The purpose of this paper is to present the results of a comparative study of two different least squares (LS) approach for identification of fractional order systems. The first one is based on repeated fractional integration and modal approach and the second one is based on Grünwald approximation. Both methods are explained in detail and identification algorithms are elaborate. Obtained results are used to initialise output error (OE) technique. Illustrative examples are presented to show the practically usefulness of the two proposed approach. Comparative remarks between the two methods are also given.

  • Twisting control algorithm for the yaw and pitch tracking of a twin rotor
           UAV
    • Authors: Seyed Mehdi Rakhtala, Mostafa Ahmadi
      Pages: 143 - 163
      Abstract: In this paper, second order sliding mode controller is used to compensate the pitch and yaw angles of multivariable (MIMO) twin rotor system. Twin rotor has six state variables including yaw and pitch angles, yaw and pitch angular velocities, and armature currents. Considering the physical structure of twin rotor, the controller aims to track the mentioned angles and stabilise their angular velocities. Two sliding surfaces are defined as the sum of tracking error of yaw and pitch angles and their integrals. The controller performance is studied in the light of tracking accuracy and steady-state error, transient behaviour and response fluctuations level, consistency. The closed-loop system performance will also be studied in the light of disturbance effect rejection, presence of uncertainty in the model, and presence of estimated practical noise. The simulation is presented for first and second order sliding mode controllers and their advantages and disadvantages will be investigated.

  • Reconfigurable adaptive fuzzy fault-hiding control for greenhouse
           climate control system
    • Authors: Essam I. El-Madbouly, Ibrahim A. Hameed, Mohamed I. Abdo
      Pages: 164 - 187
      Abstract: Modern greenhouses are equipped with various components for providing a comfortable climate for plant growth. A greenhouse component malfunction may significantly crumble the greenhouse performance and hence result in loss of production. Therefore, it is required to design a control system, which is stable, and is able to provide an acceptable performance even in a severe fault situation. In this paper, an active fault-tolerant control scheme to compensate for actuator and/or sensor faults in the greenhouse climate system is designed. The proposed control system consists of a self-tuned fuzzy PI control system, a sensitive and reliable observer-based fault detection and diagnosis (FDD) mechanism for different types of faults in the presence of system disturbances, and a robust fault-hiding-based reconfigurable control design able to compensate for faulty effects. In this approach, a set of virtual sensors and actuators are used to restore the closed-loop stability and to ensure accurate tracking of reference inputs. The efficiency of the proposed approach has been demonstrated through a set of simulation experiments on a nonlinear multi-input multi-output greenhouse climate system.

      Abstract: This paper presents a comparative study of robust nonlinear controller based on sliding mode control theory and internal model controller-based PI for VSC-HVDC transmission system. A modified sliding mode controller or 'SAT' is used to handle the uncertainties and enhance the system performance, under various disturbance conditions. The new sliding mode control compensates the influence of dynamics and chattering phenomena on the system response. It also improves the robustness of the reaching phase of the modified sliding mode control. The effectiveness of the proposed controllers is demonstrated through digital simulation studies using MATLAB/SIMULINK software package. The simulation results demonstrate that the proposed controller contribute appreciably towards improving the damping behaviour of the VSC-HVDC system under various disturbances compare to conventional PI and IMC-based PI controller.

  • Stabilisability of differential linear repetitive processes delayed
           systems with saturating control
    • Authors: Said Kririm, Abdelaziz Hmamed
      Pages: 207 - 221
      Abstract: This paper is devoted to stability analysis of differential linear repetitive processes systems with state delays and input saturation. The domain of attraction resulting from an a priori designed state feedback law is analysed using Lyapunov-Krasovskii functional approach. Both delay-independent estimation of the domain of attraction are presented using the linear matrix inequality technique. The problem of designing linear state feedback laws such that the domain of attraction is enlarged is formulated and solved as an optimisation problem with LMI constraints. Numerical examples are used to demonstrate the effectiveness of the proposed design technique.

  • Design of adaptive PID controllers based on adaptive Smith predictor for
           ultra-local model control
    • Authors: H. Thabet, M. Ayadi, F. Rotella
      Pages: 222 - 238
      Abstract: In this paper, an ultra-local model control approach based on adaptive Smith predictor is proposed. The design of adaptive PID controller takes into account the estimation of variable time delay which is compensated by the addition of an adaptive Smith predictor. The purpose of this paper is to solve the online estimation problem of time delay thanks to the proposed identification method of ultra-local model parameters. A performance comparison between the proposed control approach and the Smith predictor control with classical PID is carried out. The numerical simulation results of the thermal process study with severe constraints and operating conditions show the superiority of the adaptive PID controller. The robustness with respect to noises, disturbances and system parameter uncertainties of control approaches are highlighted.
