A digital PWM control for switched reluctance motor drives

Switched reluctance motor (SRM) drives are highly non-linear. Therefore, their control over a wide speed range has unique difficulties. Conventional linear controllers are not ideal for SRMs. In this paper, a novel digital PWM control for SRM drives is presented. By treating the system digitally, the controller switches between two different duty ratios to get the desired speed. The proposed control technique is very easy to implement and has a wide speed range. Simulation and experimental results are presented to verify the proposed digital control approach.
