Abstract

Abstract: This article proposes the linear quadratic regulator with integrator to perform the power control delivered to the grid by a doubly fed induction generator. For this, the machine model is presented as state equations, where the imposition of the synchronous orientation by the stator flux allows power decoupling and consequently individual rotor current control. The controller is optimized by a particle swarm with adaptive inertia weight search algorithm. Experimental results showed the robustness and efficacy of this controller when applied in a wind energy conversion system.
