Wind energy conversion systems control using T-S fuzzy modeling

Abstract

The paper investigates the wind energy conversion systems (WECS) control problem. To deal with the intrinsic nonlinear behavior of WECS, a T-S fuzzy model is proposed. The method assumes that the wind speed is unmeasurable. Then an H8 output feedback controller is designed by taking into account directly wind speed as perturbation. The design conditions are given in linear matrix inequalities (LMI) terms which can be solved efficiently using existing numerical tools. To illustrate the effectiveness of the given algorithm (wind disturbance rejection), the proposed synthesis techniques are applied to a dynamic model of the WECS.
