说明：  A switched reluctance motor (SRM) is suitable for many variable-speed and servo-type applications, and is getting increasing attention in the motor drive industry. However, the SRM has highly nonlinear characteristics since the developed torque of the SRM is a nonlinear function of both phase current and rotor position, and the SRM always operates with magnetic saturation to maximize torque/mass ratio. In this simulation, the PI speed controller was applied to the speed loop of the SRM .
