Sensorless Fault Tolerant Control Based On Backstepping Strategy For Induction Motors

Résumé

In this paper, a fault tolerant control for induction motors based on backstepping strategy is designed. The proposed approach permits to compensate both the rotor resistance variations and the load torque disturbance. Moreover, to avoid the use of speed and ux sensors, a second order sliding mode observer is used to estimate the ux and the speed. The used observer converges in a nite time and permits to give a good estimate of ux and speed even in presence of rotor resistance variations and load torque disturbance. The simulation results show the e ciency of the proposed control scheme.
