Abstract
A feedforward compensator for induced vibration is disclosed. Controlled motions in an actuator induce mechanical disturbances in a surrounding cabinet. The feedforward compensator allows such disturbances to be compensated for without the need of a vibration sensor. The compensator provides a feedforward compensation signal configured to compensate for a mechanical disturbance predicted to be induced by a controlled motion of the actuator, and applies the feedforward compensation signal to a signal that controls the motion of the actuator.
