Abstract

This paper demonstrates an innovative invention: "digital self-powered autonomous" vibration-suppressor using a digital micro-processor. Our invented unit is a completely self-powered vibration-suppression unit that does not require any external power-supply at all. Nevertheless, this digital, self-directive, and self-powered approach enables the vibration suppressor to be programmable and thus versatile in control scheme. The digital-autonomous suppressor is much more advanced and progressive than clumsy analog-autonomous ones. This digital system can be implemented in MIMO (multiple-input multiple-output) systems to suppress even complicated structural vibration. To our best knowledge, this invention is the first one in the world, and quite useful for various applications to energy-saving or energy-shortage systems, such as large space structures, artificial satellites, and isolated lunar bases, which all are subject to long night-time.
