Dynamic behaviour of 12/8 switched reluctance motor

Abstract

In the recent decades, the switched reluctance motor has been a good candidate in automobile industries for its simplicity and ruggedness, its small inertia and high torque and speed range. Having a simple construction with neither winding nor magnets in the rotor, the SRM has a doubly salient stator synchronous and singly excited throw it the torque is simply developed due to reluctance variation. Nevertheless, the switched reluctance machine still has incapacities such as a ripple torque and acoustic noise. Thus, many issues for hybrid electric vehicle application requirements have been developed to reduce the torque ripple and ensure more stability and less noise. Based on static characteristics as torque and flux linkage, the nonlinear model of switched reluctance motor is represented for a 12/8 SRM model aimed to a starter alternator application in this paper using MATLAB/Simulink to recognize an optimal choice of turn-off angle and suitable controller and converter for the torque and speed optimization. The dynamic model explained next is using a measured data of static torque flux linkage and characteristics obtained with a software been used for simulation in the MATLAB/Simulink data base.
