Abstract: To eliminate the error of conduct phase switching and the influence of magnetic saturation when the traditional pulse injection method is adopted, this paper presented a new switched reluctance motor control method based on subregional inductance. In this method, a single phase is selected as the identification phase, and the corresponding inductance profile is divided into three regions: magnetization region, freewheeling region, and pulse injection region. Combined with the real-time sampling of current information characteristics, the mathematical relationship between rotor position and inductance can be built. Then, the fitting function is reconstructed using the optimization of the inductance curve and the rotor estimation error caused by inductance saturation is reduced effectively. This strategy realizes the identification of multiple rotor positions with better estimation accuracy compared with the traditional method using three phase-inductance intersection points. Finally, the simulation and experimental results verify the correctness and feasibility of the proposed control strategy.
