摘　　要：针对多电机驱动控制问题,构建了2台对称六相PMSM的反串联规则。对于串联系统中的谐波耦合问题,建立了2台对称六相PMSM反串联系统的虚拟多电机耦合模型,揭示了对称六相PMSM中偶次谐波对串联系统解耦运行的影响机理,指出转子结构的对称性设计能够消除该种谐波耦合,使系统实现解耦运行。通过对转子结构对称的2台对称六相PMSM反串联系统进行了变负载仿真,证明了该串联系统解耦运行的可行性。As to the drive control problem of multiple motors,the inversed series connection rule of symmetrical six-phase PMSM two-motor system is proposed.For harmonic coupling problems,fictitious multi-machine coupling models of symmet⁃rical six-phase PMSM two-motor inversed-series connection system are established.The influence mechanism of the even order harmonics in the symmetrical six-phase PMSM on the decoupling operation of the series system is revealed,and it is pointed out that the symmetrical design of the rotor structure can eliminate the harmonic coupling and realize its decoupling operation.A variable load simulation is carried out on two symmetrical six-phase PMSM inversed-series connection system with symmetrical rotor structures,which proves the feasibility of decoupling operation of the system.
