Implicit fault tolerant control technique based backstepping : application to induction motor

Abstract EN

The aim of this paper is to apply a resent implicit fault tolerant control (FTC) technique based backstepping to induction motor (IM).

Mathematical models of the motor, the disturbances as well as the faults signals have been developed.

Using these models, the dynamic behavior of motor is studied.

A backstepping control is then synthesized and applied to the system.

Based on the simulation results, it is evident that this control law is robust to the unknown torque load and parametric variations but is not to the rejection of the faults effect.

In order to detect and compensate this later, a recent FTC technique is then studied and applied to the motor model.

The performances of the applied technique are highlighted by simulations.
