This paper reviews recent patented developments in active vibration isolation. First of all, the fundamental limitations of passive vibration isolations are established, to understand the motivations to introduce active control in vibration isolation. Then, the main different active strategies are presented using simple systems and compared. Finally, several specific issues are listed and briefly discussed.

Keywords: active stabilization, active vibration isolation, inertial reference, sky-hook spring, hard mount, multi-dimensional active isolation, sensor limitations, vibration suppression, vibration, seismic vibrations
