摘    要:为提高五相永磁同步电机故障状态下的转矩性能,提出了一种基于铜耗最小的解耦容错控制方法。在磁动势不变原理与铜耗最小原则的基础上,求解出故障后电机的容错电流,然后根据所求得的补偿电流,推导出电机缺相后的降维变换矩阵,从而建立故障后五相永磁同步电机的数学模型,实现故障后电机的解耦控制。采用联合仿真的方法来验证所提出的容错控制算法。仿真结果表明,缺相后电机的转矩脉动得到了有效的降低,实现了电机的无扰容错运行。

关 键 词:五相永磁同步电机   开路故障   铜耗   解耦   容错控制

Abstract:To improve the torque performance of five phase permanent magnet synchronous motor under fault condition, a decoupling fault tolerant control method based on minimum copper loss was proposed. The method which based on the principle of the constant stator magnetic motive force and minimum copper loss could be used to calculating the faulttolerant current. Then, according to the compensation current, the reducedorder transformation matrix had been deduced. In the rotating coordinates, the mathematical model of the fivephase permanentmagnet synchronous motor was established. And the decoupling vector control method is achieved. The effectiveness of the proposed faulttolerant control algorithm is verified by the method of cosimulation. The results of the simulation showed that the proposed faulttolerant control could reduce the torque ripple under the faulty condition.
Keywords:fivephase permanent magnet synchronous motor (FPMSM)   opencircuit fault   copper loss   decoupling   faulttolerant control
