Tuning of Fractional-Order PID Controller for Electro-Hydraulic Servo Valve System

Abstract

Last few years, some researchers have researched Fractional Order PID (FOPID) controllers that produce better system responses than conventional PID. In this paper, look for new parameter values of fractional-order PID in the electro-hydraulic servo valve system and observe system response performance. In industries such as aircraft often use an electro-hydraulic servo valve system (EHSV). Judging from the importance of EHSV in the industry, it can have a significant impact if it has efficient performance.To improve the performance controller from conventional PID is converted into FOPID controller to find system performance with Particle Swarm Optimization (PSO) and Genetic Algorithm (GA). The results of the simulation provide rise time, settling time, and overshoot values to analyze, expected to have a faster and better response than the previous controller.
