Torque ripple minimization with current oriented method for switched reluctance motor

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 can effectively reduce the torque ripple. It has been experimentally verified that this method can effectively reduce the torque ripple and improve the position precision of the servo control system.
