This paper presents a robust PI tracking control strategy with mixed H2 and H∞ performance for general non-Gaussian systems based on the square root B-spline model for the probability density functions (PDFs).The main objective is to design a generalized proportional-integral (PI) control strategy such that the PDF can follow a target one with the enhanced robustness. Different form the previou...

The Proportional-Integral-Derivative Controller is widely used in industries for process control applications. Fractional-order PID controllers are known to outperform their integer-order counterparts. In this paper, we propose a new technique of fractional-order PID controller synthesis based on peak overshoot and rise-time specifications. Our approach is to construct an objective function, th...

This paper realized the 2-DOF controller structure for first order with time delay systems. The co-prime factorization is used to design observer based controller K(s), representing one degree of freedom. The problem is based on H∞ norm of mixed sensitivity and aims to achieve stability, robustness and disturbance rejection. Then, the other degree of freedom, prefilter F(s), is formulated as fi...

This paper introduces a brand-new, inspired optimization algorithm (the chaotic billiards (C-BO) approach) to effectively develop the optimal parameters for fuzzy PID techniques enhance dynamic response of solar–hydrogen drive an induction motor. study compares fuzzy-PID-based C-BO regulators based on particle swarm (PSO) and PI-based PSO provide speed control in solar–hydrogen, induction-motor...

In this paper, a statcom without any energy storage devices is proposed to compensate network voltage during disturbances. This statcom utilizes a matrix converter in its topology which eliminates the DC-link capacitor of conventional statcom. The modulation method for matrix converter which is used in this paper is space vector modulation. There are some methods to improve power quality for se...

This work deals with the design, analysis and simulation of shunt active power filter SAPF, which compensate harmonic currents, and reactive power under balanced supply network. An optimal control theory for currents compensation based on particle swarm optimization is developed in this paper. The SAPF is connected in parallel with a nonlinear load which has caused current harmonics in industri...

Abstract: In this study, the control of a non-linear system was realized by using a linear system control strategy. According to the strategy and by using the controller coefficients, system outputs were controlled for all reference points with the same coefficients via focused references. In the framework of this study, the Lorenz chaotic system as non-linear structure, and the discrete-time P...

This paper presents a sensorless system drive on primary flux oriented control (PFOC) and secondary flux oriented control (SFOC) for the linear induction motor (LIM) with taking into account end effect. Extended kalman filter (EKF) is applied to estimate LIM speed by measuring motor voltages and currents. In order to achieve desirable dynamic and robustness motor performance instead of traditio...
