Abstract :
A LMI-based approach is proposed to design a quadratically stable flux observer for an induction motor. The resulting observer is a parametrically varying dynamic system that insures a L2-gain attenuation between the exogenous input and the flux estimation error of the augmented plant. Its performance is evaluated and compared with those of the Verghese observer.
