Abstract：

Servo press is a new developing trend in forming equipment. Aiming at the nonlinearity, time-variability and time lag existing in servo system, the fuzzy PID control method was applied to conduct the position servo press control system. A fuzzy PID controller was built up to achieve the PID parameter setting of regulator using the Borland C++ Builder. The experimental results of step response and sinusoidal signal response show that this method could effectively raise the response speed，reduce overshoot and steady-state errors, and have powerful ability of restraining external disturbance. The control algorithm using fuzzy PID control has the better performance than that of traditional PID control algorithm, which is an effective method to improve servo presss position control.
