基于自谐波信号注入的无刷同步起动/发电机转子位置估计同步解调方法

This article proposes a novel synchronous demodulation method of rotor position estimation for brushless synchronous starter/generator (BSSG) at zero and low speed based on self-harmonic signal injection. Instead of the conventional external voltage signal injection, second harmonic in the field winding of the main generator is employed as the indirectly injected high-frequency signal into the rot...
