摘要：

A sensorless control strategy was proposed for switched reluctance motor, which includes initial rotor position monitoring, start-up operation, position reconstruction and speed regulation. First, the current rise time of phase current within the hysteresis bandwidth at fixed position was measured off-line and stored as initial threshold for the start-up process; then the initial position was partitioned by comparing the current rise time of each phase within the hysteresis bandwidth by small current injection. The motor was then started with the initial threshold, which was updated according to actual operating process. The newly updated threshold was employed as the detection feature for the next period. Then, the rotor position was reconstructed and the speed was estimated according to detected threshold signal. And commutation and speed regulation were achieved accordingly. In the end, simulation and experimental results were conducted presented to demonstrate effectiveness and accuracy of the proposed sensorless strategy. © 2024 Editorial Department of Electric Machines and Control.
