An active vibration absorber is provided for absorbing vibrations in a member (21). An inertial mass (22) is mounted on the member with a stiffness (24) between the member and the mass. A force actuator arrangement (23) 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 (29) 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 (25) provides for at least one second signal indicative of a reaction of the inertial mass. A control arrangement (30) is provided for controlling the force actuator arrangement using the at least one first signal and the at least one second signal.
