Design of CNC Feed Servo System Based on Fuzzy PID

CNC machine tool is the basic equipment for the development of high-tech industry and high-tech industry. Feed servo system is an important part of CNC system. The matching of drive control parameters is related to the performance of NC system. Servo drive system is an important part of CNC system. Under the same mechanical properties, the matching degree of servo parameters and mechanical properties determines the machining accuracy and quality of the machine tool. Therefore, how to match parameters quickly and effectively has always been the focus of research. A fuzzy adaptive PID controller combining fuzzy control and PID control is designed and applied to the control of NC servo system. The controller has good control performance. The simulation data show that the fuzzy adaptive PID controller has good accuracy and strong robustness.
