ABSTRACT:
An active force actuated vibration isolation system uses a velocity sensor in the form of a velocity-sensitive geophone to sense payload velocity and modifies the geophone signal to control the force applied to oppose the vibration. The modified signal effectively reduces the inherent resonant frequency of the geophone and avoids instability.
