In this paper, a novel torque ripple minimization method, namely, sliding mode variable structure is proposed for switched reluctance motor (SRM). The total reference torque is calculated by the speed error via the sliding mode variable structure controller, and the expected phase torque will be got through the Torque Sharing Function. Then make margin calculations between the expected phase torque...
The current of switched reluctance motor (SRM) affects not only the stable position of rotor, but its torque. In this paper, an analytic expression of current oriented method in terms of torque and rotor position is presented. With the accurate control of current, rotor would be stabilized on any position except for aligned and unaligned position. Combined with a nonlinear fuzzy model, this method...
Due to the reluctant effect that exists between the stator and the rotor and its conception, the torque of switched reluctance motor (SRM) has a ripple waveform. Hence it is necessary to reduce these undulations, which are undesirable and harmful for a best fonctionnement of system. In order to minimize these undulations, we present in the follow paper the current hysteresis control of the SRM supplied...
