Adaptive fuzzy-PID simulation for the feeding servo system of numerical controlling tool

Since traditional PID control strategy can not meet the control requirements of the NC feed servo system,a fuzzy adaptive PID controller is designed based on the traditional PID control combin-ing fuzzy control theory.By applying Fuzzy control theory,PID parameters are changed in real-time,which make the system with better adaptive ability and robustness.Meanwhile dynamic simulation for the feed servo system is done under the MATLAB,which results show that the performance of this adaptive fuzzy PID controller is much better than the conventional PID controller,even in the external disturbance and system conditions change with characteristics of fast response and good robustness.
