Abstract
A controller for a floating wind turbine is adapted to cause the wind turbine to extract energy from wave-induced motion of the turbine. The controller controls the rotor speed of the turbine by controlling the torque of the load presented to the rotor such that the rotor speed varies in response to wave-induced motion.
