Application of Backstepping Strategy for Induction Motor Control

Abstract

In this paper, a novel field-oriented induction motor using backstepping control is presented. Backstepping control is proposed for replacing the existing PI controller to obtain high performance motion control systems, for the speed, flux and currents control loops. Stability analysis based on Lyapunov theory is also performed to guarantee the convergence of the speed tracking error from all possible initials conditions. Computer simulations confirm that the proposed backstepping control scheme offers improved performance in terms of the trajectory tracking ability to time-varying reference input.
