Design and Simulation of Fuzzy Self-Adjusting PID Controller of the Electrohydraulic Servo System

摘要：

A fuzzy self-adjusting PID (proportional integral differential) controller of the electrohydraulic servo system is designed and simulated.The controller applies the fuzzy reasoning algorithm into the traditional PID control.The controller can modify the PID factors and some parameters of the electrohydraulic servo system dynamically based on the running condition.The controller is simulated with Simulink of Matlab.The simulation test shows that the controller can select the proper parameters dynamically as the input displacement and loads be changed.It can improve the control effects of the electrohydraulic servo system under nonlinear and time-variation condition.
