An extensive research activity have been devoted to the problem of induction motor control over the last decade. Most of the proposed controllers have been designed under the assumption that the motor is unsaturated. As this is not the case in realistic situations the expected performances, especially during transient periods, may not be achieved. In this paper, an adequate model that rigorously accounts for the saturation feature for an AC machine with uniform air-gap. Then, a controller is designed using the backstepping technique combined with the usual flux orientation. The obtained controller is shown to meet its objectives, namely motor regional stabilization, reference speed tracking and reference flux regulation.
