To reduce the effect of estimation position angle error caused by mutual inductance on sensorless control of switched reluctance motor (SRM) in clear command channel mode, a SRM rotor position estimation method is presented. Using this method, the effect of mutual inductance can be eliminated without measuring mutual inductance. First, different working states are analysed. When working at single-phase excitation, mutual inductance can be ignored, inductance model method is used to estimate the position angle. When working at two-phase excitation situation, mutual inductance is non-zero, based on flux linkage-difference a new method is used to eliminate mutual inductance influence. Finally, the proposed method is verified by experiments. Experiment results show that compared with the mutual inductance ignored methods, the proposed method has higher estimation accuracy. This method can realise stable and reliable running of SRM sensorless control in wider speed range.

The paper presents a position estimation method of the Switched Reluctance Motor(SRM) based on inductance model through FEA. The phase inductance of SRM is seriously nonlinear. Based on FEA, Fourier analysis result of phase inductance shows that more than three times harmonic contents are smaller. Ignoring more than three times harmonic, the simplified inductance model is expressed. Then a new rotor position estimation method is presented, which is based on the inductance model. Experiment results show that the effectiveness of the method proposed is verified, and under different saturated conditions, the method can accurately estimate the rotor position of Switched Reluctance Motor.
