<p>The invention relates to a device for vibration control of a structure having-two mass bodies (10,20) which are mounted so as to be rotatable about in each case one rotational axis (12,22), wherein the two rotational axes extend in the same direction and the centre of gravity of each mass body has a spacing (r1,r2) from the associated rotational axis,-a drive which sets each mass body (10,20) in a circulating rotational movement, at least one sensor (40) which measures a movement or acceleration of the structure (30) and-a controller which, on the basis of the measured movement or acceleration, controls at least one of the following variables:-the rotational angle (phi1, phi2) of the rotational movement of at least one mass body (10, 20),-the spacing (a) of the rotational axis (12) of a mass body (10) from the rotational axis (22) of the other mass body (20).</p> |
