Abstract: | Synchronization and parameter identification of a unidirectional star-network constructed by discrete spatiotemporal chaos
systems with unknown parameters are studied. The synchronization principle of the network and design method of parameter recognition
law are introduced. The function to be determined in the parameter recognition law and the range of adjusting parameter are
obtained based on Lyapunov stability theory. Not only global synchronization of the network is realized, but also the unknown
parameters in spatiotemporal chaos systems at the nodes of the network are identified. Discrete laser spatiotemporal chaos
model is taken as each node of the network, and simulation results show the effectiveness of the synchronization principle
and parameter recognition law. |
