The first part, the speed commands are stepped at time 0.5 s from 0 rpm (standstill) to 1400 rpm (rated speed) and standstill to 120 rpm for high and low speed operations, respectively, both in DTC and the offered control method. The load torque is suddenly changed from no load to full load at time 2 s, then returns to no load again at time 4 s in each simulated situation. After that, the speed, torque and magnitude of stator flux responses of DTC and the offered control method are compared. For a fair comparison, the simulations use the same load torque, speed commands and PI controller gains for speed controllers.
