Description
Summary:In this article, a novel rotor position estimation method based on the second-order generated integrator (SOGI) is proposed for sensorless starting control of the brushless synchronous machine (BSM) with the indirect high-frequency signal injection method for the aircraft. The high-frequency signals are injected into the stator field windings of the main exciter, and the response signals coupled to armature windings and the rectifier are indirectly injected into the field windings of the main generator. The envelope demodulation method is proposed for the rotor position estimation, and the unitized filter design for the more accurate rotor position signal extraction is exploited instead of the traditional bandpass filter and low-phase filter based on the optimal parameters of SOGI. Finally, the feasibility and effectiveness of the proposed rotor position estimation method for BSM in the sensorless control are verified by both simulation and experimental results.
