Abstract

This paper presents the effect of change the switching angles values on the operation of switched reluctance motor (SRM) at no-load in aircraft applications. Turn-on θon and turn-off θoff, angles are the two switching angles that play a major role in deciding whether SRM develops positive or negative, high or low electromagnetic torque. These switching angles are considered as the main excitation parameters in SRM performance and also they support the most efficient operation through producing high value of total torque per ampere. The SRM, converter, and control system are modeled in Simulink model to demonstrate the drive system operation using MATLAB/SIMULINK software package. The simulated performance of SRM drive system is presented to analyze the effect of different switching angles on no-load performance of speed, current and torque. An optimum of turn-on and turn-off angles that ensures stable at no-load operation is recommended.
