Abstract
A vibration suppression system and method for a wind turbine comprising blades is provided. The system comprises, for each blade, a stabilization system comprising a gyroscope with a control axis extending in a first direction, a first rigid body control axis extending in a second direction different from the first direction, a second rigid body control axis extending in a third direction different from the first and second directions and a flywheel rotatable in respect of the control axis and free to move in respect of at least one of the rigid body control axes. The stabilization system comprises an actuator to apply a torque over the gyroscope, and a respective sensor to detect the motions of each blade. The suppression system comprises a control device for controlling the actuation of the actuators according to said detections, in order to suppress unwanted motions of the blades.
