Abstract
Aiming at the noise suppression of switched reluctance machine (SRM), the two-step commutation control method is improved. Combining this with pulse width modulation (PWM), the optimisation problem of the switching angle is studied and analysed and given a method to determine the turn-on angle, the zero-voltage turn-off angle and the turn-off angle of the negative bus voltage online. The control method is verified by MATLAB/Simulink simulation and experimental prototype platform. The results show that this method is simple and effective. It can achieve variable angle control, and can reduce the operating noise of the motor under different speed and load conditions. It has a high application value in the field of switched reluctance motor-type electric vehicle development.
