Abstract

This paper presents a simple technique to minimize torque ripple of a switched reluctance motor (SRM). The technique is based on the control of the sum of the square of the phase currents by using only two current sensors and analog multipliers. The control characteristics of the SRM drives are analyzed for operation of the motor in the linear region of its magnetic characteristics. The simulation and experimental results of the proposed method are given. The advantages and limitations of the proposed circuit are explained. (C) 2002 Elsevier Science B.V. All rights reserved.
