Abstract: The present invention relates to a method for controlling a wind turbine, in particular a method for controlling pitch of one or more blades of a wind turbine and related system. The method comprises collecting first data indicative of a dynamic condition of the first wind turbine blade and the rotor, the first data comprising rotor data and first deflection data, the rotor data being indicative of the azimuth position and rotational velocity of the rotor in a rotor plane perpendicular to the rotor axis, and the first deflection data being indicative of the position, speed and acceleration of one or more parts of the first wind turbine blade. Further, the method comprises calculating an expected tower clearance distance at a later time of tower passage for the first wind turbine blade based on the first data including acceleration of one or more parts of the first wind turbine blade, and performing measures to prevent tower collision, if the expected tower clearance distance fulfills a collision risk criterion.

Abstract: A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method.
