An Efficient Nonlinear Backstepping Controller Approach of a Wind Power Generation System Based on a DFIG

In this paper; we present an efficient and robust nonlinear control model for wind energy conversion system based on a doubly fed induction generator (DFIG). The aim of this work is to develop a model, which combines the vector control and the nonlinear Backstepping approach to control the currents rotor and the mechanical rotor speed of the generator in order to extract the maximum of the power produced. The robustness and performance of the system are tested and compared with classical PI controller in terms of reference tracking whatever generator parameters variations. Simulation results were evaluated and presented under MATLAB/SIMULINK Software.
