Abstract:
1. An active vibration isolation system comprising: a) a support body for bearing a load that is to be isolated; b) pneumatic vibration isolators with controllable valves for carrying the support body with respect to a base; c) position sensors for providing vertical position signals of the support body; d) a first regulating system for vibration compensation in at least one degree of freedom in translation (Xt,Yt,Zt) and in at least one degree of freedom in rotation (Xr,Yr,Zr) with at least e) a second pneumatic regulating system for vibration compensation in at least one degree of freedom selected from three degrees of freedom (Zt,Xr,Yr) that are effective in vertical direction with at least wherein at least one branch from the first regulating system to the second pneumatic regulating system is provided such that the first regulating system and the second pneumatic regulating system are coupled to act together in at least one degree of freedom of the three degrees of freedom (Zt,Xr,Yr) that are effective in vertical direction.
