| Research Abstract |
In this project, we considered the synchronization problems in networks of identical nonlinear systems with delayed couplings. In particular, we obtained the following results:
(1) We proposed a new synchronization criterion based on a frequency domain stability condition and showed that the proposed criterion is less conservative than the conventional synchronization criteria based on the Lyapunov-Krasovskii approach. Furthermore, we showed the relationship between the network structure and the synchronization condition and developed estimation methods of synchronization and partial synchronization based on the synchronization condition for two coupled systems and the eigenvalues of the graph Laplacian.
(2) We proposed an analysis and a design method for pattern formation in networks of identical nonlinear systems with delay couplings by applying the harmonic balance methods.
