Generalized predictive control robust for position control of induction motor using field-oriented control

This paper presents the study and implementation of a different field-oriented control strategy using a generalized predictive control (GPC) technique applied to the mechanic position loop aiming to obtain a system that acts in the fractional horsepower motor driver running at near zero frequency. The position and speed loops were identified to verify the system behavior and, from the model found design the GPC controller. Simulation and experimental results are shown and discussed to demonstrate the merit of the proposed approach and the performance and robustness of the algorithms have been evaluated.
