Abstract
A method and a damping device for absorbing an undesired vibration, in particular, a tremor or an oscillation, in which a base is decoupled from the vibration by a positioning actuator. A control unit registers a relative displacement of the foot and a mass caused by the vibration as a deflection of a spring element that links the foot to the mass. There is thus no need for a reference system that acts independently of the vibration to control the positioning actuator, allowing the damping device to be produced at relatively low cost. The time-delayed transfer from the spring element to the mass is also exploited to counteract the vibration before it has an undesired effect on the base.
