Aiming at the problem of the torque ripple in the development and promotion of the switched reluctance motor (SＲM)，the direct torque control (DTC) strategy is proposed in this paper for SＲM，and the realization method of DTC is presented. Due to that there is no 12/8 poles ontology model in the MATLAB，this paper uses the results of finite element analysis，combines with the torque calculation formula and the method of look-up table to establish 12/8 poles nonlinear ontology model in MATLAB，then establish overall DTC simulation model on this basis. The simulation results show that the established nonlinear ontology model and the control system model are reasonable and effective，the torque ripple suppression effect of DTC strategy is obvious，and the dynamic and static performance of the system is improved，and the effectiveness of the scheme is verified.
