An Adaptive Nonlinear Backstepping Control of DFIG Driven by Wind Turbine
Authors: , ,
Abstract: In this paper we present a new control structure to extract the maximum power of a wind energy conversion system based on the double fed induction generator (DFIG). The proposed algorithm combines the nonlinear Backstepping approach and the field orientation scheme applied to control the rotor side converter (RSC) and the grid side converter (GSC) of the DFIG. The proposed strategy is asymptotically stable in the context of Lyapunov theory. Simulations results show interesting performances of the system in terms of the reference tracking stability and the robustness against parameters variations.
