Direct instantaneous torque control combined with torque sharing function strategy for switched reluctance drive

The inherent highly nonlinearity of switched reluctance motor not only makes it difficult to eliminate torque ripple with conventional average torque control techniques, but also restricts its application in the high-performance servo systems. A novel control strategy combing direct instantaneous torque control with the torque sharing function control is proposed in this paper. In order to track the reference torque accurately, the instantaneous torque is directly controlled by a hysteresis and PWM controller with torque sharing function. The control strategy is applied to a prototype motor control system, and is verified by the experiment results.
