Parameter identification of a fractional order dynamical system using particle swarm optimization technique

Abstract: System identification is a necessity in control theory. Classical control theory usually considers processes with integer order transfer functions. Real processes are usually of fractional order as opposed to the ideal integral order models. A simple and elegant scheme is presented for approximation of such a real world fractional order process by an ideal integral order model. A population of integral order process models is generated and updated by PSO technique, the fitness function being the sum of squared… Show more

“…It can control joint angles of the robot arm and suppress vibrations of the system, simultaneously using proper loop shape. In 26 parameters of a FO controller were optimized using modified PSO that has better solution and faster search speed in contrast with GA. By using PSO in 27 , a FOPID controller was designed that has remarkable reduction in overshoot, rise time and setting time. In another approach, the PSO was applied to determine FOPID parameters with efficient search and more robust performance using for an automatic voltage regulator 28 .…”

“…Dzięki tej metodzie istnieje możliwość rozwiązywania różnych zadań analizy, syntezy, identyfikacji, diagnostyki, projektowania nowoczesnych systemów sterowania itp. [3][4][5][6]10]. Badania w dziedzinie systemów rzędu ułamkowego udowodniły, że systemy rzędu całkowitego są przypadkiem cząstkowym systemów ułamkowych.…”

“…Caputo zaproponował swoje rozwiązanie, które różni się od definicji Riemanna-Liouville'a tym, że funkcję na początku różniczkuje się z najmniejszym rzędem całkowitym n, który przekracza ułamkowy rząd j a następnie całkuje się z rzędem n-j. Doświadczenia naukowców w dziedzinie syntezy elektrotechnicznych regulatorów ułamkowych, a zwłaszcza systemów elektromechanicznych pokazują, że ułamkowy rząd składowej różniczkującej nie jest większy niż j=1 [1, 6,8,9]. Do rozwoju i korekty tej teorii w dziedzinie elektrotechniki przyczynili się: Heaviside, N. Viner i J. Carlson.…”

“…Cao [7] demonstrated the parameter optimization of a fractional order controller based on a modified PSO. In their paper, the improved PSO could achieve faster search speed and better solution compared to the GA. Maiti et al [8] employed PSO for designing fractional order PID controllers. They reduced significantly the percentage of overshoot, rise, and settling times using FOPID controllers compared to a PID controller.…”
