Three cascaded close-loop control applied to AC Servo-system is studied according to the principles of predictive functional control. Based on its closed-loop performances analyzed, the method to design the predictive functional controller is given. It sets up the structure of three cascaded close-loop predictive functional control system applied to AC Servo-system. The implementing method of cascaded control is discussed. The simulation results and the comparison with PID method show that the predictive functional control can improve controlled performances of AC Servo-system.
