Reduction of Torque Ripple in a SRM through Direct Torque Control

Abstract

Switched reluctance motors (SRMs) have several desirable features, including simple construction, high reliability, and low cost. However, one of their drawbacks is higher torque ripple. Direct torque control (DTC) is considered a useful way of controlling the torque ripple. This paper presents an approach to the design and implementation of direct torque controller for SRM using digital signal processor (DSP) and field programmable gate arrays (FPGAs).
