| Research Abstract |
The study reports herein on how we developed our innovative digital self-powered autonomous system for vibration controller using a digital micro-processor. The invented unit is a completely self-powered control 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. The digital-autonomous controller is much more advanced and progressive than conventional 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 vibrations. This is quite useful for various applications to energy-saving or energy-shortage systems. Experiments demonstrate that displacement is reduced drastically. Energy dissipation in experiments is measured by various cases.
