摘　　要：研究了一种基于SVPWM算法的九开关变换器驱动双Y移30°永磁同步电机的容错控制策略。根据九开关变换器的工作原理,得到断相后的空间电压矢量,选择合适的基础电压矢量,提出适用于断相后电机的SVPWM算法;根据断相后电机相应的约束条件,采用矢量空间解耦的方法,确定了变换矩阵,建立了单相断路的电机数学模型;仿真实验验证了该容错控制策略的可行性。A fault tolerant control strategy of nine-switch converter driving a double Y-connected phase-shift 30°permanent magnet synchronous motor( PMSM) based on SVPWM algorithm was studied. Based on the working principle of the nine-switch converter,the space voltage vector after the phase break was obtained,the suitable voltage vector was selected and the SVPWM algorithm suitable for the phase break motor was proposed. According to the corresponding constraint conditions of the motor after the fault phase,the vector space decoupling method was adopted to determine the transformation matrix,and the mathematical model of the single-phase open-circuit was established. The simulation results verified the feasibility of the fault-tolerant control strategy.
