Abstract:
A vibration-damped machine, comprising:a beam being capable of gross motion in space relative to a stationary frame,a motor for causing said gross motion of said beam in at least one direction, said gross motion tending to induce vibration in said beam,a work member mounted to said beam,a sensor device for providing at least one signal representative of said induced vibration in said beam,at least one linear-acting inertial actuator mounted to said beam, wherein said at least one linear-acting inertial actuator comprises a plurality of inertial actuators each having a primary vibration axis, wherein said primary vibration axis of each of said plurality of inertial actuators are substantially orthogonal; anda controller for processing said at least one signal and generating at least one output signal to actively drive said at least one linear-acting inertial actuator in said at least one direction at the appropriate phase, frequency and magnitude to damp said induced vibration of said beam.
