Abstract
The present invention relates to control of a wind turbine where nacelle vibration is reduced by use of blade pitching or generator torque modulation. The nacelle vibrations are reduced based on a position signal of the nacelle. An actuator signal is determined based on the position signal and applied to the actuator capable of reducing nacelle vibration. The actuator signal is gain adjusted based on a separation between the rotor frequency and tower vibration frequency.
