Velocity-proportional active vibration damping

A control program stored on a non-transitory medium and comprising machine code which, when executed by a control device operating an active vibration damper having a damping device arranged on a vibration-susceptible mechanical structure, causes the control device to operate the active vibration damper by

• capturing a temporal course of a magnitude of a movement of the mechanical structure in space over an extended time period,
• determining, based on the magnitude of the movement of the mechanical structure in space, a damping force damping a vibration of the mechanical structure, wherein the damping force is proportional at all times to an instantaneous velocity of the mechanical structure,
• determining whether a predefined natural vibration of the mechanical structure is damped in a predefined manner,
• controlling a damping drive of the damping device, which is constructed as an electric direct linear drive and arranged on the mechanical structure, commensurate with the determined damping force, and
• directly injecting with the damping drive the determined damping force into the mechanical structure so as to automatically track a proportionality factor between the instantaneous velocity of the mechanical structure and the damping force exerted on the mechanical structure, such that the natural vibration of the mechanical structure is damped in the predefined manner.
