Modeling, simulation and control of reluctance motor drives for high speed operation

Abstract

This paper presents the modeling, simulation, and control of Switched Reluctance Motor (SRM) for high-speed applications. The model of SRM is built with help of three-dimensional relationship between excitation currents, rotor position and flux linkage. The relationship makes electromagnetic torque depends not only on the excitation currents but also on the rotor position. Therefore, it is difficult to control a SRM to obtain high performance operations. In order to reduce torque ripple of the drive, we have used the Torque Distribution Function (TDF) approach and proposed a novel TDF for high-speed applications. The simulation in Matlab/Simulink using the parameters of a 60 kW 6/4 poles motor demonstrates the superiority of the novel proposed TDF method for SRM drives in high-speed regions.
