基于低频信号注入和估计励磁电流的绕线式同步起动/发电机低速区转子位置估计

Due to the reliability problems of mechanical position sensors, rotor position estimation technology is an alternative for the starting control of aircraft wound-field synchronous starters/generators. Reversible saliency and high-frequency attenuation characteristics of the main machine (MM) may lead to the failure of existing high-frequency signal-based estimation methods. In this article, low-fr...
