| 摘 要： | 单逆变器驱动对称六相永磁同步电机串联三相电机是一种新型的多电机系统。针对对称六相电机反电动势的谐波会影响串联系统的解耦控制的问题，在同步旋转坐标系下建立了对称六相电机反电动势含有最主要的2次谐波时串联系统的数学模型，分析了谐波对六相PMSM电磁转矩脉动幅值和频率的影响情况，提出了补偿反电动势谐波效应的解耦控制策略，通过变载和变速仿真证明了所提控制策略的可行性。

| Abstract: | Symmetrical six-phase series-connected three-phase PMSM driven by single inverter is a novel multi-machines system. To research EMF harmonics influence on the decouple control of series-connected system, the series-connected system mathematic models with 2nd harmonic of symmetrical six-phase PMSM under d-q coordinates are deduced. The torque ripple amplitude and frequency influenced by harmonic are discussed. The decouple control strategy based on harmonic effect compensating is presented. And the simulations with variable operating states are proposed to validate the feasibility. |
