<p>The invention relates to a device for vibration control of a structure having—two mass bodies (10, 20), each of which is rotatably mounted around a rotational axis (12, 22), wherein both rotational axes extend in the same direction and the center of gravity of each mass body has a spacing (r1, r2) from the associated rotational axis,—a drive that sets each mass body (10, 20) in a circulating rotational motion,—at least one sensor (40), which measures a movement or acceleration of the structure (30), and—a control that, based on the measured movement or acceleration, controls at least one of the following variables:—the rotational angle (φ1,φ2) of the rotational movement of at least one mass body (10, 20),—the spacing (a) between the rotational axis (12) of one mass body (10) and the rotational axis (22) of the other mass body (20).</p> |
