It is difficult to achieve the desired control in vector control system for AC motors by using the ordinary PID controller,for the control system is a complex nonlinear,strong couple,and changing system.So a fuzzy PID controller was designed based on the fuzzy control and ordinary PID principle.Simulation results show that the control system with the fuzzy-PID controller has a better dynamic steady-state performance than the system with the ordinary PID controller.
