1. A method of controlling a wind turbine comprising a tower supporting a rotor comprising a plurality of pitch-adjustable rotor blades, the method comprising:
obtaining a movement signal indicative of a vibrational movement of the tower;
determining an actuator signal based on the movement signal, the actuator signal being determined to produce a desired force to counteract the vibrational movement of the tower;
determining a pitch reference offset signal for each one of the plurality of pitch-adjustable rotor blades based on the actuator signal;
applying an integration of the pitch reference offset signals;
determining modified pitch reference offset signals based on the integrated pitch reference offset signals;
determining a pitch signal for each one of the plurality of pitch-adjustable rotor blades based on the modified pitch reference offset signals; and
adjusting a pitch of the plurality of pitch-adjustable rotor blades based on the respective determined pitch signals.
