Abstract

This paper presents a simple robust control for induction motors. The control is robust to uncertainties in the rotor and stator winding resistances, and a bounded load torque perturbation. In the proposed scheme, assuming that a nominal control law, designed with the knowledge of the plant parameters, ensures the exponential stability of the closed-loop system in the absence of parameter uncertainty, we use the Lyapunov redesign technique to design an additional feedback signal that is added to the control signal to guarantee the uniform ultimate stability in the presence of uncertainties. Simulation results are included to illustrate the performance of the control scheme
