Abstract:
A control system for compensating a hysteresis band of a switched reluctance (SR) machine having a rotor and a stator is provided. The control system may include a converter circuit and a controller. The converter circuit may be operatively coupled to the stator and include a plurality of switches in selective communication with each phase of the stator. The controller may be in communication with each of the stator and the converter circuit, and configured to monitor at least one phase current of the SR machine relative to a current threshold of the hysteresis band, determine an adjustment value based on a difference between the phase current and the current threshold if the phase current exceeds the current threshold, and compensate the current threshold by the adjustment value.
