Abstract

Sensorless starting control of the brushless synchronous starter generator by using the main exciter (ME) as a position sensor is an emerging advanced technology. The back electromotive force (EMF) of ME is the key for position estimation. The back-EMF of ME is usually obtained by the observers and thus the parameters of ME are needed. Therefore, mismatched parameters would lead to an estimation error of the back-EMF and then the rotor position. According to the waveform characteristics of the back-EMF of ME, this paper proposes a parameter-independent method to extract the back-EMF information of ME. The effectiveness of this method is verified by experiment results.
