An active vibration isolation system (10) includes a plurality of stiff actuators, such as piezoelectric motors (12a-c; 284, 350) which support a small mass (18) inside of a case (300). A passive isolator (20) is interposed between the small mass (18) and the payload mass (M.sub.p). In the instance ...

PURPOSE: To secure stability by extremely enhancing feedback loop gain of a system for actively isolating vibration up to a low frequency band, and setting the gain of the system to a low value in a resonance frequency of a supported payload and an active element. CONSTITUTION: An active vibration i ...
