An improved stator winding fault tolerance architecture for vector control of induction motor: Theory and experiment

摘要

This paper presents a fault tolerant control (FTC) for stator winding fault of induction motor. The aim of this work is to develop an algorithm which can detect the appearance of a fault in closed loop and switch itself between a nominal control strategy designed for healthy condition and robust control designed for faulty condition. In order to obtain a better performance, two robust control techniques have been tested: back stepping control based on Lyapunov theory and sliding mode control. The effectiveness of the proposed approach is verified by experimental results.
