摘要

本文提出了直接转子磁链定向异步电动机驱动的电流传感器容错控制方法。在a相或/和b相传感器失效时进行了模拟测试。该方案采用基于直流电压和转子角速度的虚拟电流传感器(VCS)算法，重构静止参照系(α-β)下的定子相电流值。提出了一种简单的电流传感器故障检测与定位算法。在不同工况下的仿真研究表明了该方法的有效性。

Current Sensors Fault Detection and Tolerant Control for Induction Motor Drive

In this paper current sensor fault tolerant control for direct rotor flux oriented induction motor drive has been presented. The simulation tests have been carried out when A-phase or/and B-phase sensors have failed. The solution proposes the use of the Virtual Current Sensor (VCS) algorithm based on the direct current (DC) voltage and the rotor angular velocity, which is reconstructing the values of the stator phase currents in a stationary reference frame (α-β). A simple algorithm for detecting and locating current sensor fault has been proposed. Simulation studies under different operating conditions of the drive showed high efficiency of the presented method.
