The paper presents fuzzy control method for permanent magnetic synchronous machine AC servo system. In the system's design, fuzzy controller was adopted as place controller, current fast track control method was adopted as current controller, PI adjuster was adopted as speed controller, which was designed according to second type system. The system capability was tremendously improved. Compared with general PID control system, the experimental and simulation results show that the design scheme has favorable dynamic and steady performance and strong robustness. And it demonstrates the reasonable and superiority of the design way.
