Sensor fault tolerant control for induction motor

Abstract

In this work we study the problem of fault tolerant controller (FTC) design for Induction Motor (IM) with field oriented control (foc) performances. (T-S) technique is employed in the aim to represent the IM dynamic. A fuzzy controller is designed to preserve the tracking performance en spite the presence of sensor fault. Using L2 optimization and Lyapunov theory the performances of the trajectory tracking are studied. In terms of LMIs constraint the observer and controller gains are calculated. Finally, to prove the efficiency of the synthesized controller scheme, a simulation results are given.
