Abstract: 

Considerable torque ripples of switched reluctance motor (SRM) is one of fundamental reasons, which restricts its application domain and consequently, invokes serious effort in its control domain. A striking feature of feedback linearization method is to transfer the original nonlinear system to a secondary linear system by means of a suitable coordinates' transformation, and then directly apply the usual methods of linear control domain. Accordingly, if the transformed linear system of SRM obtained, in addition to access to original control objective (namely, speed regulation), admissible control on torque ripple and the other secondary objectives will be achieve. In this paper, considering the usual speed control structure of SRM, a new and yet simple structure is proposed for realization of feedback linearization method that in addition to resolving the weakness of its pervious applications (including: need to have an exact model of motor, need to apply various simplifications that restrict application domain, and high volume of computation), has considerable robustness to parameter variation and uncertainty, and yet operate near optimal. simulation results that the proposed speed controller has considerable robustness and is successful in desirable speed tracking and control of torque ripple.
