| Outline of Final Research Achievements |
In general, a network system is described by the combination of (i) network structure and (ii) component dynamics. For the analysis and design of a networked system, it is usually assumed that the information on both the network structure and the component dynamics is available. It is however often violated in real situations, especially with heterogeneous components. Therefore, it is desirable to establish a framework of the structural analysis and design, i.e., analysis and design in the case where the network structure is known but the component dynamics is (almost) unknown. This study has established a series of results on the structural issues.

| Academic Significance and Societal Importance of the Research Achievements |
制御工学において１９９０年代に確立されたロバスト制御は，限られた量の変動に対しては有効な設計方法を与えた．しかしながら，サイバー攻撃のように，構成要素のダイナミクスを完全に書き換えるような変動に対しては無力であった．一方，絶対安定化ネットワーク構造が明らかになると，これまでの「ロバスト性」という言葉のもつイメージをはるかに超える，絶対的な保証に守られたシステムの設計理論が明らかになる．本課題では，そのような設計理論の基礎を与えた．
