Abstract
An active tuned vibration absorber () is disclosed for reducing vibrations in a structure, the vibration absorber comprising: a mount () for attachment to the structure; a moveable mass (); a spring arrangement () connected between the mass and the mount; an actuator arrangement () for applying a force between the mass and the mount; a first sensor () for providing a first measurement indicative of a force exerted between the structure and the mount; a second sensor () for providing a second measurement indicative of an acceleration of the structure at or proximate to the mount; and a control system () for generating an actuator driving signal for driving the actuator using the first and second measurement, wherein the control system is operable to generate the actuator driving signal to cause the first measurement and second measurement to conform to a target relationship.
