Vibration reduction will be an important contributor to the success of future earth observing platforms. Unwanted motion in the micrometer to nanometer range must be prevented from interfering with co ...

ACX proposes an alternate approach to damping for extreme environments, which uses an electrically shunted, surface mounted, smart material. This shunting approach has been most widely used in less e ...

Active Control eXperts, (ACX) Inc. proposes to design, fabricate, and demonstrate a novel hybrid vibration ccntrol actuator system capable of very precise, controllable motion. This system will combin ...

In many structures with vibration problems, the nature of the problem is uncertain, or varies over time. Thus it is not possible 'a priori to design a linear, time-invariant, (LTI) feedback control l ...
