摘要：In this paper, Self Tuning Fuzzy PID controller is developed to improve the
performance of the electro-hydraulic actuator. The controller is designed based on the
mathematical model of the system which is estimated by using System Identification
technique. The model is performed in linear discrete model to obtain a discrete
transfer function for the system. Model estimation procedures are done by using
System Identification Toolbox in Matlab. Data for model estimation is taken from an
experimental works. Fuzzy logic is used to tune each parameter of PID controller.
Through simulation in Matlab by selecting appropriate fuzzy rules are designed to
tune the parameters Kp, Ki and Kd of the PID controller, the performance of the
hydraulic system has improved significantly compare to conventional PID controller.
