This paper compares and analyzes the performance of DTC torque ripple minimization schemes of induction machine drive systems

introduced up to these days. The DTC has a problem where varied switching frequency and ripple are produced due to the hysteresis

controller. As a solution for the DTC, many methods are proposed in which the low constant switching frequency is maintained

while minimizing the torque ripples. As a result, through the PSIM simulation, the performance of the torque ripple and response

of the proposed methods are compared, analyzed, and verified.
