【Abstract】 A sliding mode variable structure control for switched reluctance motor(SRM) speed control system is presented.System performance is improved by combining the torque control inner loop and the speed control outer loop,and the acceleration estimation is also added to the sliding mode controller.The speed performance of switched reluctance motor is implemented through simulation.The results show that sliding mode control for SRM is very simple and robust,and the application of the acceleration estimation reduces the sliding mode chattering.更多还原
