Outline of Final Research Achievements

Time delays of interactions on networks induce the following two phenomena: stabilization and diversification. This study provides us some fundamental results and useful applications on these phenomena. For the fundamental results, we obtain analytical results of stabilization of delay-coupled oscillators and of instability of delay-coupled reaction diffusion systems. For the applications, we show the formation control of robotics based on dynamics of coupled oscillators and the stabilization of DC power system by delayed-feedback control.

Academic Significance and Societal Importance of the Research Achievements

我々の身の回りにある「遅延」は,システムのパフォーマンスを低下させるネガティブな要因として扱われてきた.本研究は,この「遅延」がポジティブに活用できるのでは?という視点で,遅延が誘発する現象について,理論的な「基礎研究」と実用を目指した「応用研究」に取り組んだ.独創性の強い取り組みであるため,本成果をさらに深く・広く展開すれば,今までは発想できなかったような機能を持つシステムが創造できるかもしれない.
