Abstract

This paper exhibits a novel invention: "digital self-powered autonomous" vibration-suppressor using a digital micro-processor. The invented unit is a completely self-powered vibration-suppression system that does not require any external power-supply at all. Nevertheless, this digital, self-directive, and self-powered approach enables the system to be programmable and thus versatile in control scheme implementation. The digital-autonomous suppressor is much more advanced and progressive than previously proposed analog-autonomous ones that are clumsy and awkward. This digital system can be implemented in multiple-input multiple-output systems to suppress even complicated structural vibration, such as multi-modal vibration. To our best knowledge, our 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 vulnerable to long night-time.
