Switched Reluctance Motor (SRM) implement is constrained by high torque ripple. An effective torque ripple compensation method is proposed based on sliding mode current compensation (SMCC). According to the relationship between torque and current of the SRM, a current compensation with a sliding mode controller is designed. The input of the sliding mode controller is the difference between the reference torque and instant torque, and the compensation current is obtained as the output through the calculation of the sliding mode surface. The total current is the sum of linear conversion current and compensation current. The Lyapunov stability criterion proves the stability of the sliding mode compensation. In MATLAB simulation environment and low-speed operation of the motor, the effectiveness of the proposed method is proved. Compared with PD current compensation method, the efficiency of this method in current compensation is improved, and the torque ripple can be effectively reduced.
