In this paper, an output optimization control of variable pitch wind turbines is discussed. Based on adaptive exptemum control scheme proposed by Krstić et al., such a pitch control system that maximizes output of wind turbines below rated wind speed, and regulates output of wind turbines above rated wind speed is proposed for variable pitch wind turbines. In order to apply the designed control system to practical wind turbines, first, a two-blades micro wind turbine with variable pitch structure was manufactured and modeling was performed through the wind tunnel experiment. Second, computer simulator was created based on the determined mathematical model of the wind turbine, besides the control system was applied to the simulator and effectiveness of the proposed control system is verified through the simulation works. Finally, to evaluate the practical use of the control system, experimental works were carried out for the manufactured wind turbine.
