A reduced torque ripple controller for direct torque control of induction machines

Direct Torque Control (DTC) of induction machines (IM), based on hysteresis comparators and selection table, suffers from variable switching frequency and large torque ripple, especially at low speed. This is because the rate of change of torque and flux and hence the time taken for the torque and f...
