Abstract: The present invention relates to a method of controlling a wind turbine having at least one blade and a controller, including: detect location of foreign material adhered to the blade by sensors mounted on the blade and communicatively coupled to the controller; determine the resonance mode of the blade to be excited based on the location of the foreign material by the controller; and excite the blade to the resonance mode; wherein the resonance mode is one higher than the first order resonance mode. The present invention also relates to a wind turbine using the method.
