摘　　要：针对双三相电机驱动系统开路故障容错控制问题,依据双三相电机空间矢量解耦理论,提出一种简易的容错控制方法,即虚拟健全系统。研究了双三相永磁同步电机驱动系统单相缺相和开关管故障,给出了基于电流补偿的容错控制和最小铜耗容错控制的参考电流,其中以绕组总铜耗最小为优化目标得到的容错参考电流为全局最优铜耗解。采用重复控制器实现非常规容错控制参考电流的有效精确跟踪。提出的容错控制方法可确保系统容错切换过程中,整体控制框架、数学模型、调制策略均保持不变,仅需改变参考电流,降低了容错控制的复杂度。同时,提出的容错方法也可以扩展到其他相数多相电机的容错控制。To solve the problem of open circuit fault-tolerant control of dual three-phase motor drive sys-tem,a simple fault-tolerant control method,virtual healthy system,was proposed based on the space vec-tor decoupling theory of dual three-phase motor.The single open-phase and open-switch fault of dual three-phase permanent magnet synchronous motor drive system were studied,and the reference current of fault-tolerant control based on current compensation and minimum copper losses fault-tolerant control were given,in which the fault-tolerant reference current obtained with the minimum total winding copper con-sumption as the optimization objective is the global optimal copper consumption solution.The repetitive controller was used to realize the effective and accurate tracking of the reference current of unconventional fault-tolerant control.The proposed fault-tolerant control method can ensure that the overall control frame-work,mathematical model and modulation strategy remain unchanged in the process of fault-tolerant switching.Only the reference current needs to be changed,which reduces the complexity of fault-tolerant control.At the same time,the proposed fault-tolerant method can also be extended to the fault-tolerant control of other multiphase motors.
