为提高双电机驱动系统的可靠性，提出了一种改进的五桥臂双永磁同步电机直接转矩控制（P-DTC）方案。首先，五桥臂双永磁同步电机驱动系统的拓扑结构进行说明。为了阐明P-DTC的分析，提出了三相驱动系统的标准DTC方案。五桥臂双永磁同步电动机驱动系统的操作被分为三种情况下，根据开关矢量联盟的定义。与现有的直接转矩控制方案（R-DTC）相比，P-DTC可以最大限度地减少有源开关矢量向零开关矢量的替换。当这种替换无法避免时，P-DTC使用建议的主从选择原则来最小化系统误差。与R-DTC相比，P-DTC具有转矩脉动小、调速范围宽、转矩增长响应快等优点。在耦合模式和独立模式下进行了实验，所得结果验证了P-DTC的有效性
To enhance the reliability of two-motor drive systems, this paper proposes an improved direct torque control (DTC) scheme (P-DTC) for five-leg dual-PMSM drive systems. First, the topology of a five-leg dual-PMSM drive system is illustrated. To clarify the analysis of the P-DTC, the standard DTC scheme for three-phase drive systems is presented. The operation of a five-leg dual-PMSM drive system is classified into three situations according to the definitions of the switching-vector unions. Compared with the existing DTC scheme (R-DTC), the P-DTC can minimize the replacement of active switching-vectors to zero switching-vectors. When this replacement cannot be avoided, the P-DTC uses a proposed master-slave selection principle to minimize the system error. Comparing with the R-DTC, the P-DTC has lower torque ripples, a wider speed range and a faster torque increasing response. Experiments have been carried out in the coupling and independent modes, and the effectiveness of the P-DTC is verified by the obtained results
