Abstract
A vibration control system for damping vibration of an body to be isolated against vibration. The body is supported on a movable base through the medium of vibration-damping supporting structure. The control system comprises a vibration sensor for detecting vibration of the movable base. An inverse vibration signal generating circuit includes a digital sensor and in supplied with a detection signal outputted from the vibration sensor for generating a signal with a waveform to cancel out the vibration of the body through interference therewith. An actuator is connected operatively to the movable base and the inverse vibration signal generating circuit for converting the signal derived from the latter into a mechanical vibration to be applied to the body.
