| Abstract: | Synchronization and parameter identification of globally coupled network constructed by discrete spatiotemporal chaos systems with unknown parameters are studied. The control law designed by Milosavljevic is extended, and applied to the identification of unknown parameters in spatiotemporal chaos systems at the nodes of the network and the study of global synchronization of the network. The one-dimensional convective equation with spatiotemporal chaos behaviour in physics is further taken for example to imitate analysis. |
| Keywords: | synchronization parameter identification globally coupled network spatiotemporal chaos |
