Fuzzy Logic PID Based Control Design for Permanent Magnet Synchronous Motor Servo System

This paper mainly deals with a fuzzy logic proportional-integral-derivative (PID) based controller for a permanent magnet synchronous motor (PMSM) system. To greatly improve the dynamic characteristics of the PMSM and refrain from undesired disturbance due to parameter diversification and load disturbance, a novel fuzzy switching algorithm is created and a combined fuzzy PID controller is further developed to ensure smooth transition over a wide range of speeds. Numerical simulation and physical experiments on the PMSM servo system confirm that the proposed controller has been endowed with the advantage of both fuzzy logic controller and PID controller, which yields enhanced dynamic feats and stability.
