In this study, a control logic of wind turbines by using fuzzy function is proposed and the effect of control logic on the power performance and the load on supporting structure is investigated. By using proposed control logic which uses fuzzy function and use the gain values calculated by loop shaping, the fluctuation of the rotor speed can be reduced. By adding additional loop from acceleration of the nacelle is introduced and it is shown that this method can effectively add additional damping and resulting damage equivalent fatigue load of the tower base moment is reduced while the other fatigue load does not increase. This indicates that the tower acceleration feedback is a effective tool to reduce tower load.
