摘要

This paper deals with detecting of stator winding inter-turn short-circuits fault of induction machine operating under two control methods namely the backstepping control and the integral sliding mode control. The fault detection method is introduced, based on analysis of measured three-phase stator currents and estimated ones given by an unknown input observer. The difference between these behaviors, namely residuals, are used to detect the inter-turn short-circuits fault. Simulation results obtained from an induction machine with inter-turn short-circuits fault working under backstepping control and integral sliding mode control are presented.
