An induction motor sensor fault detection and isolation based on higher order sliding mode decoupled current controller

Abstract : This paper presents a novel decoupled current-control method for induction motor (IM) based on higherorder sliding mode (HOSM) controller. In the proposed scheme,the decoupled control of d−qcurrents does not require theknowledge of the speed. The HOSM controllers play the samerole as the compensation voltages produced by a decouplingcompensator. Based on this observation, the speed is estimatedaccurately through algebraic calculations by avoiding the low-pass filtering. The estimated speed is then employed for faultdetection and isolation. Simulations on a 1/4-hp three-phaseIM in the presence of noise highlights the performance of theproposed approach
