| Outline of Final Research Achievements |
Throughout this project, we have attempted to develop a theoretical framework for synchronization in networks of nonlinear systems with sampled-data couplings. In particular, we obtained the following results: 1) We derived a sufficient condition for synchronization of nonlinear systems with mutual sampled-data couplings. 2) We proposed an estimation method of synchronization condition for undirected networks of sampled-data coupled systems. 3) We developed a stability criterion for nonlinear systems with uncertain time-varying delays, and we proposed a stabilization design method for such systems. 4) We also investigated the effect of the use of asynchronous sampled-data in networks on synchronization. 5) We clarified the relationship among the couplings strength, sampling interval, time-delay, and synchronization.

近年，複数のシステムがネットワークを介して接続され，大規模ネットワークシステムを構成するようになってきている．複数の同一システムが情報ネットワークを介して接続されるとき，ネットワーク全体の振舞いを検討することは重要となる．本研究では，そのように情報ネットワークを使用した人工物のネットワークシステムを構成することで生じるサンプル値結合ネットワーク全体が生じる挙動を解析する手法を明らかにしている．
