Abstract
Thus getting better PID parameter is not easy if we adopt traditional PID control.To solve this problem,a fuzzy PID controller was presented into the loop control of CNC feed servo system.The results of simulation show that comparing with the traditional PID controller,fuzzy PID control has smaller overshoot,higher precision and robustness,improving the dynamic performance of servo system.
