考虑交叉耦合磁饱和的内置式永磁电机在线多参数辨识改进方法

A novel online multiparameter identification method is proposed for interior permanent magnet (IPM) machines considering cross-coupling magnetic saturation. The identification method is based on the combination of small-signal impedance model and fundamental frequency signal model under dq-axes. To analyze the nonlinearity of IPM machines, cross-coupling magnetic saturation effect is introduced in...
