Abstract

The paper presents a method to design optimally tuned fractional order controller for position tracking control of EHSS (Electro-Hydraulic Servo System). A proposed controller has simple structured and is based upon fractional order model of system. The controller parameters are tuned using PSO (Particle Swarm Optimization) technique. Simulation results on linear and non linear system show significant improvement in performance of FOPID (Fractional Order Proportional-Integral-Differential) controller compared to classical PID (Proportional-Integral-Differential).
