<p>A damping system for damping oscillation of a moving structure (6) comprises a rotatable mass (12), a motor arranged to drive the rotatable mass, a movable mass (36), a motor arranged to drive the movable mass so as to move its centre of gravity, sensing means (38) arranged to detect movement of the structure and control means arranged to control the motors in response to detected movement of the structure (6) thereby to damp oscillation of the structure.</p> |
