Abstract

A robust control algorithm for wind turbines subjected to a wide range of wind variation, grid disturbance and parameter uncertainties is presented. The algorithm utilizes fuzzy systems based on “Takagi-Sugeno” (TS) fuzzy models to approximate nonlinear systems. TS fuzzy systems are classified into three families based on the input matrices and a robust controller synthesis procedure is given for each family. This algorithm combines the merits of: (i) the capability for dealing with non-linear uncertain systems; (ii) the powerful Linear Matrix Equalities (LME) approach to obtain control gains. The control scheme is tested for different real profiles of wind speed pattern and provides satisfactory results.
