Controlador preditivo generalizado com anti-windup aplicado a um sistema de geração eólico baseado em DFIG

Abstract

This paper presents a continuous time predictive current controller applied to DFIG-based wind turbine. The controller design is based on the rotor current model and its tuning is carried out by adjusting two parameters. The first parameter is responsible for the continuous-time horizon and the second parameter tunes the filter, which is responsible to reduce electromagnetic torque/ instantaneous power ripple. Moreover, it addresses windup problems since the saturation model is part of the loop control. The simple tuning procedure and anti-windup scheme are the benefits of the proposed controller. The robustness of the design controller is verified by increasing the rotor’s resistance, so that the uncontrolled instantaneous power oscillations are reduced when compared with the conventional PI controller. Experimental results were carr
