Abstract:

This paper describes a new position sensorless control method of 3-phase SRM based on the complex plane expression of phase inductance. The rotor position is simply obtained without magnetic characteristics of the motor and additional hardware. In this method, assuming the phase inductance waveform to be sine wave, the rotor position is obtained by computing the angle of the space vector of inductance. The space vector of inductance is computed from excited phase currents. Experimental results show the validity of the proposed method.
