    摘要:

    六相永磁容错电机发生一相或多相开路故障后,如不调整剩余相的电流,转矩脉动会很大,电机性能会明显降低。为使电机单相开路后能保持正常状态下的性能,以[WTBX]A[WTBZ]相开路为例,建立了该电机单相开路情况下在静止五相坐标系上的数学模型,对其进行虚拟坐标变换后,实现了电机故障状态下的解耦控制,可对电机进行矢量控制。建立了仿真模型,仿真结果表明:一相开路情况下,通过调整剩余相电流的幅值和相位,电机仍能正常运行,且保持了正常状态下的性能,实现了电机的容错控制。

    Abstract:

    When open circuit failure occurs in single-Phase or multiphase of the six-phase permanent magnet fault tolerant motor, if the current flows of the remained phases are not adjusted, the torque ripple will be too large and the performance of the motor will be obviously reduced. In this paper, assuming that phase A is at fault, in order to preserve the performance of order, the mathematic model under five-phase stationary coordinate is set up. By performing dummy coordinator transformation for it, the decoupling control of the fault motor is realized, and vector control of it is possible. The simulation model is also set up and the simulation result indicates that, by changing the value and phase of the current flows of the remained phases, the motor can still operate in a normal way and preserve its performance in a normal state, therefore, the fault tolerant control of the motor comes true.
