Comparative performance analysis of hysteresis current control and direct torque control of 4 phase 8/6 switched reluctance motor drive

Abstract

The Switched Reluctance Motor drives have been widely used in special applications like conveyer belts, compressors, vacuum cleaners etc., because of advantages like simple construction, no winding on rotor, high speed operation and high temperature handling capability. But its operation is not spread to the other applications because of presence of high torque ripple. The torque ripple can be minimized by adopting the Direct Torque Control Technique. In DTC technique, flux and torque are maintained within the set of hysteresis bands by applying suitable Space Voltage Vectors. This paper makes the comparative performance analysis of Switched Reluctance Motor drive with Hysteresis Current Control and Direct Torque Control techniques. The detailed simulation results based on MATLAB / SIMULINK is also presented. © 2011 Springer-Verlag.
