摘　　要：利用交流电机一般理论和电机矩阵分析方法,从级联式无刷双馈电机的基本结构和电磁关系出发,分别建立了四种不同的动态数学模型三相静止坐标系数学模型、任意速度两相旋转坐标系数学模型、转子速度两相旋转坐标系数学模型、双同步速度两相旋转坐标系数学模型,并对它们各自的特点进行了分析。以建立的转子速度两相旋转坐标系数学模型为例,对该电机进行了仿真实验,从而验证了模型的正确性,为该类电机的特性分析及其控制策略研究奠定了理论基础。Based on the general principle of AC machine and matrix analysis of electrical machines,combining with the structure and the electromagnetic relationship of cascade brushless doubly-fed machine （ CBDFM）, four different dynamic mathematical models of CBDFM were derived respectively,which included three-axis static coordinate mathematical model, any speed two-axis rotating coordinate mathematical model, rotor speed two-axis rotating coordinate mathematical model and double synchronous speed two-axis rotating coordinate mathematical model. The characteristics of these models were discussed. As an example, simulation tests were carried out with the rotor speed two-axis rotating coordinate mathematical model. The results verify the correction of the models. The proposed models provide a theoretical foundation for the characteristic analysis and control strategy research about CBDFM in the future.
