Design of an SRM Speed Control Strategy for a Wide Range of Operating Speeds

Abstract

This paper presents a speed control strategy for a switched reluctance machine (SRM). Two control strategies are compared to select the most appropriate control that allows the SRM to operate in wide-speed-range operation. The proposed strategy is first designed to control the speed in discontinuous conduction mode and is then extended to operate in continuous conduction mode as well. In this paper, the transition from three different operating modes is detailed, and the experimental results validate the proposed strategy.
