In this work, a current sensors fault tolerant control system (FTCS) for induction motor traction drives is proposed. The FTCS uses a single observer for the detection and isolation of disconnection and gain faults occurred in a single or two current sensors available in the drive. Moreover, the observer signals are used for the control reconfiguration within a field-oriented control strategy. The effectiveness of the FTCS (detection, isolation and reconfiguration) and the performance of the control strategy after different faults and perturbations is verified by simulation results using an electric vehicle model.

IM 牵引驱动器基于单观察者的电流传感器容错控制


在这项工作中，提出了一种用于感应电机牵引驱动的电流传感器容错控制系统（FTCS）。 FTCS 使用单个观察器来检测和隔离驱动器中可用的单个或两个电流传感器中发生的断开和增益故障。此外，观测器信号用于磁场定向控制策略内的控制重新配置。使用电动汽车模型的仿真结果验证了 FTCS（检测、隔离和重新配置）的有效性以及不同故障和扰动后控制策略的性能。
