Abstract

This paper aims to model the entities of a Doubly Fed Induction Generator (DFIG) based Wind Turbine (WT), to design and then synthesize the command part using the Backstepping algorithm with integral action (IBS).  The main rule of this method is to take some state variables as virtual controls, then to design an intermediate controller. It consists in controlling the BTB converters so as to master the active and reactive exchange of power with the undisturbed utility grid, and this in the case where the maximum power available in the wind is harvested (MPPT control) and also in case this harvesting is limited to the rated power conversion chain (Pitch Control). In order to evaluate the performance of the designed controller by the IBS algorithm, a series of simulations is carried in the MATLAB / SIMULINK. A comparative study with conventional PI regulators is evoked.
