Abstract

This paper analyzes the impact of using the Gopinath observer on the robustness of current and torque model predictive controls for three-phase squirrel-cage induction motors. The performance of the two controllers are compared using a magnetic flux estimator based on the voltage model and the Gopinath’s observer through simulations for the dynamic behavior of the machine when errors are introduced in its resistance values.
