摘要: 分析了旋转变压器故障对永磁同步电机控制系统和车辆运行的影响。针对旋转变压器的故障隐患,研究了一种基于脉振高频信号注入法和柔性开关函数滑模观测器的全速度范围无传感器控制算法作为容错控制,在旋转变压器发生故障之后代替硬件位置检测,保证车辆继续安全行驶,避免交通事故的发生。通过仿真和实验验证了该算法的有效性。

Abstract: The effects of resolver faults on PMSM control system and electric vehicle were analyzed.Aiming at eliminating the threat of the resolver faults and ensuring the driving safety, a full-speed range sensorless control algorithm based on high-frequency signal injection method and soft switching function sliding mode observer was studied as fault-tolerant control. The sensorless control took over the original control system after resolver failure and ensured the safe operation of the vehicle.The effectiveness of the algorithm was verified by simulation and experiment.

Key words: fault-tolerant control, sensorless control, high-frequency signal injection, sliding-mode observer, permanent magnet synchronous motor (PMSM)
