Abstract
A method of controlling a wind turbine blade of a wind turbine comprising: providing data comprising a plurality of pitch angles of the wind turbine blade and corresponding expected power coefficients for the wind turbine, each pitch angle corresponding to a maximum expected power coefficient for a degradation state of the wind turbine blade; obtaining a current power coefficient of the wind turbine; determining a desired pitch angle for the wind turbine blade, the desired pitch angle being equal to a pitch angle from the dataset corresponding to an expected power coefficient equal to the current power coefficient; and changing a pitch angle of the wind turbine blade to the desired pitch angle.
