Outline of Final Research Achievements

Considering a suitable network structure for vibration mitigation problems, we found that the structure of oscillator networks does not have a macro-structure, but a single oscillator that composes the network should have a micro-structure for the problems. Then, we summarized the design method of the oscillator having the micro-structure and published two papers in an international journal: one discusses the essential role of an oscillator in a closed-loop system, and another one discusses the relationship of an oscillator and fractional derivative. Furthermore, to install the designed oscillator network, the experimental apparatus of the pendulum system was manufactured.

Academic Significance and Societal Importance of the Research Achievements

本研究成果を通して，システム設計を構造-機能主義的に行う場合，その機能や用途に応じて，その構造を観察する尺度（ミクロからマクロまで）を変更する必要があることがわかる．これは，工学上の多くの問題に当てはまる法則であり，複雑かつ巨大な系の根幹を理解するために，システム設計者がその尺度をうまく調整するが重要であること示唆している．これが本研究の学術的意義である．
