摘　　要：针对多台定子(N≥2)上下并联布置共用一个次级结构的多定子直线感应电机,采用电压/电流空间矢量及其向量形式建立电机等效电路模型及其控制器模型。借助于控制器模型中电机次级动子板输出的机械功率,得到多定子直线感应电机输出电磁推力的计算表达式,并推导出适用于多定子直线感应电机的间接矢量控制方程。将该模型和控制算法应用于某型轨道交通列车试验线,实验结果表明,列车启动阶段速度超调量不超过1.10%,验证了理论分析的正确性。Multi-primary linear induction motor （LIM） adopts the structure of N primaries （ N is an inte- ger and N≥2） sharing just one secondary. Based on the space vectors of voltage and current, the equiv- alent circuit model and its control model of multi-primary LIM were established. By dint of the kinetic en- ergy power of the motor secondary gained from the control model, the mathematical expression of multi- primary LIM＇ s electromagnetic force was obtained. Also, the indirect vector control equations which can be used for multi-primary LIM were given. The model and indirect vector control algorithm were applied to an experimental railcar line. The experiment results present that the velocity overshoot of the railcar during it starts is less than 1.10% , which identifies the correctness of the theory.
