Adaptive Fuzzy PID Control for Switched Reluctance Motor Direct Drive Servo Hydraulic Press
Aiming at the serious saturation and dead zone nonlinearity, time-variability and time lag existing in pump controlled cylinder electro-hydraulic servo system droved by SRM (switched reluctance motor) directly, the fuzzy PID control method was applied to conduct the position servo control of hydraulic press slider. According to the influence rule that the PID parameters impact upon the response characteristic of electro-hydraulic servo system, the fuzzy self tuning module that adjusted the PID parameters adaptively based on the error and change in error was designed. The simulation and experimental results of step response and curve tracking showed that this method could effectively raise the response speed and accuracy of pump-controlled cylinder system, reduced overshoot and steady-state errors, and had powerful ability of restraining external disturbance.
