摘　　要：基于冗余自由度独立控制和相序转换规则,实现多台多相电机的串联控制,提出一种由单台逆变器驱动一台双三相永磁同步电机和一台两相永磁同步电机的串联系统,建立了两台永磁同步电机串联系统解耦数学模型和相序转换规则,研究了串联电机间基波磁动势的相互影响关系,采用空间矢量调制技术对串联系统电机的变速、变载进行驱动控制。仿真结果表明:单逆变器驱动双三相和两相电机串联系统可以独立运行,转速和负载的变化对另一台电机没有影响。A series-connected drive system supplied by a single inverter was presented,consisted of a dual three-phase permanent magnet synchronous motor（ PMSM） and a two-phase PMSM,based on the principle of utilizing the additional degrees of freedom in multiphase motors to achieve the series-connected control of multiphase motors. Detailed mathematical modeling of series-connected dual three-phase and two-phase PMSM drive system was established,as well as the phase transformation rule,and the analysis on magnetic potential of the two motors was studied. The motors of series-connected system were controlled by space vector pulse widths modulation（ SVPWM） technology with variable speed and load. The simulation results indicated that the independent control of the series-connected dual three-phase and two-phase PMSM drive system supplied from a single inverter is applicable,and the variable speed and load of one motor have no effect on another one.
