An adaptive backstepping controller of doubly-fed induction generators

In this article, we focus on the design of a robust control structure to extract the maximum power of a wind energy conversion system based on the Doubly-Fed Induction Generators (DFIG). The proposed algorithm combines the nonlinear approach Backstepping with the field-oriented control (FOC), the true and virtual control signals have been synthesized using a single channel for controlling the rotor side converter (RSC). This system will be adjusted online according to a law of adaptation deduced from the analysis of the stability in the sense of Lyapunov. The simulation results will be provided to strengthen the effectiveness of the proposed approach.
