More Information
Summary:An active vibration absorber is attachable to a structure incorporating a positioning system which serves to vibrate the structure during its operation. The active vibration absorber comprises a mounting portion for attachment to the structure, an inertial mass that is resiliently coupled to the mounting portion and a force actuator which is operative to controllably move the inertial mass relative to the mounting portion. The force actuator is configured to move the inertial mass relative to the mounting body according to a motion profile during a motion cycle of the positioning system in order to attenuate vibrations in the structure. The motion profile is determined from a motion command which is operative to drive the positioning system during the motion cycle.
