Device for oscillation monitoring of a structure having - a mass body which is mounted so as to be rotatable about a rotational axis and whose centre of gravity is at a distance from the rotational axis, - a controller having a first sensor which senses an actual value for an angular speed and/or for an angular acceleration of the mass body in a predetermined angular range of a rotational movement of the mass body about the rotational axis, and a second sensor which senses a characteristic variable for oscillation of the structure, wherein the regulating means determines, from the sensed values of the first and second sensor, a setpoint value for the speed and/or acceleration of the mass body in the predetermined angular range, - and a drive which drives rotational movement of the mass body in accordance with the setpoint value or values of the controller in the predetermined angular range and is driveless outside the angular range. |
