航空三级起动/发电机在低速区域无需高频信号注入的转子位置估计

The changeable magnetic saliency of main machine (MM) in aviation three-stage stator/generator (ATSG) makes it difficult to implement the sensorless starting in the low speed region by the machine saliency-based methods. To estimate the rotor position of ATSG (which is also the rotor position of MM), a novel rotor position estimation method based on the harmonic currents in the main exciter (ME) s...
