Abstract: The present invention relates to methods and apparatus for removing or substantially reducing negative damping effects on a floating wind turbine. An operating point signal is received and a gain scheduling parameter is determined based on the received operating point signal. An input signal is then gain scheduled by the gain scheduling parameter and based on at least the gain scheduled input signal the negative damping effects on a floating wind turbine can be removed or substantially reduced.
