Abstract

The invention relates to a method (900) for making an angle of attack correction signal (139) available for a predetermined rotor blade (210) of a plurality of rotor blades of a wind turbine (110). The angle of attack correction signal for modifying a signal (145) is provided for controlling an individual angle of attack of the rotor blade. The method (900) comprises the following steps: reading in (910) a rotor blade position signal (120) which represents an angular position (Ω1) of the rotor blade relative to a rotational axis (310) of the rotor of the wind turbine and/or reading in a rotational speed (ω) of the rotor blade about the rotational axis (301). The method (900) further comprises a step of determining (920) the angle of attack correction signal (139) for the predetermined rotor blade of the wind turbine using a correlation between an angular position and an angle of attack correction factor saved in a memory (137), the angle of attack correction signal representing the angle of attack correction factor which, when used, prompts correction of the signal (145) for controlling the individual angle of attack for the predetermined rotor blade so that an impact of a torque (M1) onto the predetermined rotor blade is matched with an impact of a torque (M2, M3) onto the at least one further rotor blade of the wind turbine, the determination being carried out using the read-in rotor blade position signal and/or the read-in rotational speed.
