Abstract
An active vibration absorber is provided for absorbing vibrations in a member. An inertial mass is mounted on the member with a stiffness between the member and the mass. A force actuator arrangement applies a force between the inertial mass and the member. A damping arrangement provides for damping of a resonance of the active vibration absorber. A first sensor arrangement provides at least one first signal indicative of at least one movement and/or stress related parameter for the member and a second sensor arrangement provides for at least one second signal indicative of a reaction of the inertial mass. A control arrangement is provided for controlling the force actuator arrangement using the at least one first signal and the at least one second signal.
