A CNC machine tool's feed servo mechanism is a dynamic electromechanical coupling system. It is difficult to correctly model the control mechanism due to the characteristics of time-varying parameters, load disturbances, and motor non-linearity. Intend to provide an approach where a fuzzy adaptive PID controller is designed by combining a PID controller with a fuzzy controller based on the mathematical model of the CNC machine tool fed servo system. Then intend to apply this controller to control the feed servo system to gain better control performance. The simulation results for the same are expected to show that this method not only has no static distortion, but also has a fast response with little overshoot, accounting for the high stability and accuracy of the fuzzy adaptive PID controller.
