摘要 对于安全要求高的电力驱动系统,其电机应具有容错性能。为提高永磁容错电机在系统正常工作时的控制性能,在分析其结构特点的基础上,建立起电机在旋转坐标系下的数学模型,并实现电流、磁链、转矩的解耦控制。通过观察磁链、转矩、转速和电流波形,验证了控制策略的可行性和有效性。 The motor drive should have the function of fault tolerance in case that a critical safety was inquired in the electric driving system. In order to improve the control performance of the fault-tolerant permanent magnet motor in the normal operation, the mathematical model of the motor was established in the rotating coordinate system based on the analysis of its structural features, as well as the decoupling control of current, flux and torque was realized. Trough observation on the waveforms of flux, torque, speed and current, the feasibility and effectiveness of control strategies were verified.
