Synchronization of complex dynamical networks by the incremental ISS approach

We apply the theory of incremental input-to-state stability to the problem of synchronization in a complex dynamical network of identical nodes, using chaotic nodes as a typical platform. The proposed technique can achieve chaos synchronization using only partial state/output information in the sense that it does not require all nodes to have access to the state/output information from the seed node that produces the reference orbit for network synchronization. Examples and simulations demonstrate the applicability and effectiveness of the new synchronization method.
