Abstract：Aiming at the torque ripple problem，direct instantaneous torque control was applied to switched reluctance motor. Speed

control system was designed on the basis of four phase 8/6 switched reluctance motor（SRM）. Then the direct instantaneous torque control

（DITC）system is built using Matlab/Simulink. A 2-D lookup table T(i,θ) in Matlab/Simulink was built to obtain the feedback torque.

Finally，the model was simulated by using of speed PID controller. The results show that the DITC which is considered as an effective

control method can not only reduce the torque ripple effectively but also enhance the dynamic and static performance of SRM.

Key words：switched reluctance motor（SRM）；direct instantaneous torque control（DITC）；hysteresis controller；torque ripple restrain
