  • Optimal preview control design of pneumatic servo system: a
           comparative analysis
    • Authors: Randeep Kaur, Jyoti Ohri
      Pages: 1 - 17
      Abstract: This paper describes the development of a preview controller based on optimal control theory for positioning control of a pneumatic servo system. The preview theory of tracking control using the future information has been studied extensively but did not get enough applications in the field of servo control systems, used in modern industrial processing, that will increase the accuracy and efficiency of the industrial product. In the pneumatic servo system, the position of pneumatic cylinder is the command input and its future information can be known a priori. The proposed control system is composed of feedback from the state of the plant and feed-forward from the reference signal by using future information. The validity of the proposed control system is confirmed by simulation results and comparative analysis is done with standard optimal control. Simulation results imply that good performance and good phase characteristics can be obtained using optimal preview controller.

  • Stabilisation of a rotary inverted pendulum system with double-PID and LQR
           control: experimental verification
    • Authors: Teng Fong Tang, Shin Horng Chong, Kee Kiat Pang
      Pages: 18 - 33
      Abstract: Rotary inverted pendulum (RIP) system is an under-actuated system. The RIP system consists of a pendulum, which is rotating freely in the vertical plane. A swing-up action using a pivot arm in the horizontal plane would then result in the pendulum to achieve upright equilibrium point. This paper describes the design of double proportional-integral-derivative (PID) controls with a linear quadratic regulator (LQR) controller for the stabilisation control of a RIP system. Besides, the dynamic model of the RIP system is described too. The LQR controller was tuned using Taguchi method of design of experiments (DoE). The double-PID controller was designed using Ziegler-Nichols second method, which the LQR controller is embedded in the RIP system to improve the stabilisation performance. The effectiveness of the double-PID and LQR controller is clarified with a RIP experimentally. The proposed controller has demonstrated succeed stable the pendulum within 0.5 degrees in three seconds and the rotary arm within 22.5 degrees.

  • A distributive approach for position control of clamps in a reconfigurable
           assembly fixture
    • Authors: Olayinka Olabanji, Khumbulani Mpofu, Olga Battaia
      Pages: 34 - 51
      Abstract: Hydraulic actuator is a type of clamp used in a reconfigurable assembly fixture for exact positioning and effective immobilisation of workpiece during the assembly process. However, due to their nonlinearity, there is a need to design a control system for their effective performance. This study presents a distributive approach to mathematical modelling and position control of multiple hydraulic actuators used as a clamping system in a reconfigurable assembly fixture. The electrohydraulic system is verified experimentally in order to observe the synchronisation of the hydraulic actuators. The mathematical model of the system is developed in the Simulink environment. A Simulink model of the system is developed from the mathematical model and simulated with a fuzzy-PID controller in order to obtain the response of all the actuators and other operating characteristics of the system. Simulation results are shown graphically in order to verify the theoretical development.

  • Stability analysis and robust synchronisation of fractional-order
           modified Colpitts oscillators
    • Authors: Kammogne Soup Tewa Alain, Ahmad Taher Azar, Romanic Kengne, Fotsin Hilaire Bertrand
      Pages: 52 - 79
      Abstract: Based on the stability theory of the fractional order system, the dynamic behaviours of the uncertain Colpitts oscillator with fractional order-derivative is studied. Furthermore, based on the extended bounded real lemma, the robust controller is obtained using the drive-response synchronisation concept together with the Lyapunov stability theory formulated using the fractional Lyapunov direct method where the fractional-order <i>q</i> belongs to 0 < <i>q</i> < 1. In order to bring out the dynamic behaviour of this system, their phase portraits, the bifurcation diagrams and the Lyapunov exponent are simulated. Moreover, in this work, an approximated solution for both systems to show that the solution of such a system can be represented as a simple power-series function is provided. This study equally provides a systematic procedure to highlight the simplicity and flexibility of the suggested control approach. Simulations with both parameters uncertainty and external disturbance show the applicability and the efficiency of the proposed scheme.

  • Synthesise of MPC controller for uncertain systems subject to input and
           output constraints: application to anthropomorphic robot arm
    • Authors: Imen Dakhli, Elyes Maherzi, Mongi Besbes
      Pages: 80 - 97
      Abstract: This paper proposes a synthesis of a dynamic controller under constraints. It is based on model predictive control (MPC) approach and resolution of a convex optimisation problem with linear matrix inequalities (LMI). The controller guarantees the closed-loop stability for polytopic time-varying uncertain systems. Conditions are provided for the controller design based on the parameter dependent Lyapunov functions (PDLF). A new demonstration is developed based on the relaxation technique, to include a slack variables <i>G<SUB align="right">i</i>. The new LMI's formulation offers an additional degree of freedom for the controller design. Input and output constraints are also taken into account during the design of the controller. This approach allows varying and adjusting the dynamic of system by taking into account input/output constraints.
      Keywords: model predictive control; MPC; dynamic controller; linear matrix inequality; LMI; parameter dependent Lyapunov functions; PDLF; input/output constraint

      Abstract: In this paper, the problem of robust stability analysis for a class of uncertain systems with interval time-varying delay and nonlinear perturbations is studied. In order to develop a less conservative stability condition, a Lyapunov-Krasovskii functional (LKF) comprising quadruple-integral term is introduced. A novel delay dependent stability criterion in terms of linear matrix inequalities (LMIs) is given by using a new delay-partitioning approach and reciprocally convex combination technique, which is derived by integral inequality approach (IIA). Compared with the existing literature, this criterion can greatly reduce the complexity of theoretical derivation and computation. Finally, three well-known numerical comparative examples are given to verify the superiority of the proposed approach in reducing the conservation of conclusion.
