Aiming at indirect vector control for AC regulating system, a fuzzy PID speed controller that combines advantages of fuzzy control with PID control is designed. Based on fuzzy reasoning, the design principle, design procedures and fuzzy roles for the speed controller that can adjust PID parameters online are introduced. Simulation results show the system performances that are obviously enhanced by using the speed controller. The controller has a high value of practical application.
