Vibration Control of In-Wheel SRM for Electric Vehicle Applications
نویسندگان
چکیده
The Switched Reluctance Motor (SRM) processes great application potential in In-Wheel Motor (IWM) electric vehicles (EV). However the problem of vibration and noise is always a disadvantage of this kind of motor. By utilizing the analytical Fourier fitting method, a convenience method for modeling In-Wheel Switched Reluctance Motor (IW SRM) is proposed for EV applications. And the negative vibration and noise effect of IW SRM on vehicle is investigated according to the unbalanced residual lateral force. Then corresponding control methods are proposed, modified and compared. The proposed combined vibration feedback control of current chopping with PWM can effectively reduce the SRM residual force and ensure the required vehicle speed, though some small low frequency force response is induced.
