RESEARCH ON TORQUE RIPPLE MINIMUM OF INDUCTANCE MOTOR BASED ON DIRECT TORQUE CONTROL

Due to the large torque ripple of inductance motor based on direct torque control, especially at a low speed, this paper proposes a new control strategy. On the basis of conventional direct torque control, a torque ripple minimum controller is introduced in the strategy in order to decrease torque ripple. The simulation shows that it can get good torque performance.
