Simulation and research on speed control strategy of switched reluctance motor

Aiming at nonlinear control system of switched reluctance motor speed regulating control,a fuzzy-PID double-model compound control strategy using fuzzy control theory and conventional PID regulator is presented.The design principle and method of double-model compound control are introduced emphatically,and applied in the speed control of switched reluctance motor control system.The theoretical analysis and simulation experimental results of show that this control method has better control performance comparingwith conventional PID regulator and simple fuzzy controller.The response speed and static and dynamic performance of speed regulating system is greatly improved,the robustness and anti-interference capability are slso enhanced.
