Direct Instantaneous Torque Control for SRM based on Modified PWM Control Strategy

Relatively high torque ripple present in Switched Reluctance Motor (SRM) limits its usage for electric drive applications. Even though there are various control techniques to minimize torque ripple, there is a need for further reduction in torque ripple to enable SRM for electric drive applications. In this paper, a modified PWM based direct instantaneous torque control is suggested for torque ripple minimization in SRM. The asymmetric bridge converter with unique switching method is employed in this work to implement the suggested control approach. Simulations performed with the aid of the MATLAB/SIMULINK software are used to confirm the success of proposed method.
