摘　　要：针对对称六相与三相PMSM串联系统一相开路的容错型解耦控制问题,提出了一种基于正常解耦变换的容错解耦控制策略,避免了降维数学模型的重新推导和复杂计算。以故障发生前后磁动势不变为前提,通过引入故障约束条件,使得故障前后两台电机均可以在各自的机电能量转换平面独立运行,且转速转矩保持不变。仿真结果表明,所提控制策略实现了串联系统容错型解耦控制,缺相运行时,两台电机转速转矩能够迅速跟踪给定,且可以独立调节、互不影响。A fault-tolerant decoupling control strategy for symmetric six-phase and three-phase PMSM series-connected system with one phase open failure was considered in which the re-derivation and complex calculation of dimensionality reduction mathematical models was avoided.To acquire the same magnetomotive force before and after the fault occurrence,a fault constraint was introduced.Both motors were able to operate independently while the speed and torque remains unchanged.Simulation results show that the proposed control strategy achieves fault-tolerant decoupling control of the series-connected system.In the absence of phase operation,the speed and torque of the two motors can be tracked rapidly and adjusted independently without affecting each other.
