In the paper, we apply LPV (linear parameter varying) control methodology for the rotational speed control problems of wind turbines. Our goals are extracting maximum power in the region below the rated wind speed and maintaining the rated power in the region over the rated wind speed. Effectiveness of the LPV control is shown by means of numerical simulations, compared with results by conventional controls
