基于多级结构的绕线式同步起动/发电机低速区转子位置估计

This paper proposes a novel on-line rotor position estimation method for an aircraft wound-field synchronous starter/generator (WFSSG) in the low-speed region. The method is based on the fact that mutual inductance between stator and rotor windings of the main machine (MM) varies with the rotor position, so it is independent of magnetic saliency. High-frequency (HF) rotating voltage is imposed in ...
