摘　　要：针对对称六相与三相PMSM串联系统的解耦控制问题,基于串联系统的数学模型,在二相旋转坐标系下进行了漏感压降补偿,并基于坐标变换和控制量叠加得到了逆变器期望输出。在解耦控制的工程实现方面,充分考虑了逆变器电压、电流限制,提出1种直流母线电压分配方法,提高了系统运行的可靠性。实验证明,所提控制策略能够实现2台电机在负载或转速突变情况下的解耦运行。For the decoupling control problem of symmetrical six-phase and three-phase PMSM series-connected system,the voltage drop caused by leakage inductance is compensated based on the series system mathematical model in two-phase rotating coordinate system,and expected output of the inverter is obtained based on coordinate transformation and control variable superposition.As for the engineering implementation,limitations of inverter voltage and current are fully considered,a method for allocating DC bus voltage is proposed to improve the reliability of system operation.Experimental results demonstrate that the proposed control strategy is capable of achieving decoupling operation of two motors under abrupt changes in load or speed.
