Active Vibration Control
نویسنده
چکیده
In order to motivate the use of active vibration control, consider the future interferometric missions planned by NASA or ESA (one such a mission, called ”Terrestrial Planet Finder” aims at detecting earth-sized planets outside the solar system; other missions include the mapping of the sky with an accuracy one order better than that achieved by Hypparcos). The purpose is to use a number of smaller telescopes as an interferometer to achieve a resolution which could only be achieved with a much larger monolythic telescope. One possible spacecraft architecture for such an interferometric mission is represented in Fig.1; it consists of a main truss supporting a set of independently pointing telescopes.

One of the best vibration control methods using smart actuators are semi-active approaches which are as strong as active methods and need no external energy supply such as passive ones. Compared with piezoelectric-based, magnetostrictive-based control methods have higher coupling efficiency, higher Curie temperature, higher flexibility to be integrated with curved structures and no depolarizati...
