PWM Current Controller for Switched Reluctance Motor Drives

Abstract

Current control is vital in SRM drives. Conventionally, hysteresis modern law is applied for modern manage in SRM drives, but it has a few drawbacks which include high sampling fee requirement, sensitivity to switching EMI noise, and ranging switching frequency. In this paper, a digital lifeless-beat PWM contemporary controller for SRM drives is proposed. An observer is delivered to assure each speedy response and balance of the lifeless-beat modern-day controller. An progressed present day sampling method is designed to have a extra accurate present day sampling and to avoid PWM put off on top of things loop.
