A controller is provided for a floating wind turbine including a rotor with a number of rotor blades connected to a generator. The controller includes an active damping controller for calculating one or more outputs for damping both a first motion of the floating wind turbine in a first frequency range and a second motion of the floating wind turbine in a second frequency range based on an input of the first motion and an input of the second motion, The controller is arranged to calculate an output for controlling a blade pitch of one or more of the rotor blades and/or for controlling a torque of the generator based on an actual rotor speed, a target rotor speed, and the one or more outputs from the active damping controller such that both the first motion and the second motion will be damped.
A controller for a floating wind turbine comprising a rotor with a plurality of rotor blades connected to a generator, wherein the controller comprises:
A method of controlling a blade pitch and/or a generator torque of a floating wind turbine, wherein the floating wind turbine comprises a rotor with a plurality of rotor blades, the method comprising:
