基于正弦电流注入的双三相永磁同步电机在线多参数辨识方法

This letter elaborates an accurate online parameter identification method for dual three-phase permanent magnet synchronous motors. For resistance and inductance identification, sinusoidal currents are strategically injected into the dq-/xy-planes. Second-order generalized integrator-based quadrature signal generators perform the extraction and differentiation of signals. These techniques eliminat...
