摘要
Based on intersection angle compensation of conducting phase and non-conducting phase inductance, a sensorless control method for switched reluctance motor (SRM) is proposed to solve the problem of inaccurate estimation of rotor position due to the magnetic saturation. Firstly, the functional relationship is constructed between the on-phase saturated current and the angle offset of inductance intersection points and their reference positions. The corresponding phase-inductance intersection points are then corrected according to the functional relationship and the on-phase saturated current measured in real time, thus the accurate position angle of phase-inductance intersection points are obtained; secondly, The speed of SRM can be calculated by the corrected intersection angle, and the rotor position of SRM is obtained. The proposed method can effectively improve the estimation accuracy of the rotor position due to the real-time correction of the intersection position of phase inductance. Finally, the feasibility of the proposed method is verified by simulations and experiments. © 2019, Electrical Technology Press Co. Ltd. All right reserved.
