Summary:

This paper deals with the design of a predictive-integral current controller for wind generators connected to the grid. The goal is to achieve a decoupled control of d- and q-axes current components at the connection point, which results in a decoupled control of the active and the reactive power exchanged between the generator and the grid. Furthermore, the control system is designed in order to achieve a deadbeat closed-loop system. The robustness of the closed-loop dynamic response and the active and reactive-power coupling when system-modelling errors exist are studied. Simulation and experimental results will be presented to validate the main contributions of this work.
