The present invention relates to a blade pitch controller for a floating wind turbine structure, wherein the floating wind turbine structure may include a support structure supporting a rotor having a number of blades. The controller may include standard blade pitch control means and active damping means. The standard blade pitch control means is arranged to control a blade pitch using a transfer function between a rotor speed error and the blade pitch. The active damping means is arranged to further control the blade pitch on the basis of a speed of a point on the wind turbine structure by converting the speed of a point on the wind turbine structure into a rotor speed error and using the same transfer function that is used in the standard blade pitch control means to convert the rotor speed error into a correction to the blade pitch.
A blade pitch controller for a floating wind turbine structure comprising a support structure supporting a rotor having a plurality of blades, the controller comprising:
