Abstract：Torque ripple is one of the main shortcomings of switched reluctance motors. Direct instantaneous torque control (DITC) can effectively suppress the torque ripple of switched reluctance motors (SRM). However, the special double-salient pole structure makes the internal magnetic circuit of the motor very complex, which makes the calculation of electromagnetic torque very difficult. In order to obtain the accurate feedback of the torque of the motor in actual operation, this paper calculates the torque under the different rotor position and phase current by using the ANSYS software of Maxwell3D, then torque-current inverse model is set up. According to the characteristics of the motor and practical experience, the torque controller in two states is designed based on the electrical mode of alternating conduction of the single and double phases of the motor. Through simulation, it is proved that the torque ripple can be effectively controlled within a certain error to achieve the torque ripple suppression effect.
