Abstract

An active vibration damper has a damping device arranged on a vibration-susceptible mechanical structure. A force can be injected directly into the vibration-susceptible mechanical structure with the damping device. A damping force which damps a vibration of the mechanical structure is determined by a control device of the active vibration damper with reference to an absolute movement of the mechanical structure in space. A damping drive of the damping device which is arranged on the mechanical structure is activated by the control device in accordance with the determined damping force such that the determined damping force is injected into the mechanical structure with the damping drive. The control device determines the damping force such that the damping force is proportional at all times to the instantaneous velocity of the mechanical structure.
