Valve Electro-Hydraulic Servo Opening Control Based on Fuzzy PID Control
In view of the problems existing in the electro-hydraulic servo opening control system,such as nonlinearity,load disturbance and time variability,in our present study the electro-hydraulic servo opening control system of butterfly valve was taken as the research subject,AMESim software was used to build the physical model of the system,MATLAB software was used to build the control model,and the two were jointly simulated.Furthermore,the control performance of conven-tional proportional-integral-derivative control(PID control)and self-tuning fuzzy PID control was compared.The experi-mental results show that compared with the conventional PID control,the electro-hydraulic servo opening control system with self-tuning fuzzy PID control mode had smaller overshoot,shorter adjustment time,greatly improved accuracy,and also had good robustness to disturbance.
