Considering the characteristics of the nonlinearity and the strong coupling the control structure that fuzzy control is used as the outer loop of the speed and the vector control is used as the inner loop of the current is presented .

针对两相混合式同步电动机非线性、强耦合的特点，提出了采用模糊控制作为速度外环控制器，采用 矢量控制作为电流 内环控制器的结构。
