Decentralized adaptive synchronization in nonlinear dynamical networks with nonidentical nodes

摘要

For a network of interconnected nonlinear dynamical systems an adaptiveleader-follower output feedback synchronization problem is considered. Theproposed structure of decentralized controller and adaptation algorithm isbased on speed-gradient and passivity. Sufficient conditions of synchronizationfor nonidentical nodes are established. An example of synchronization of thenetwork of nonidentical Chua systems is analyzed. The main contribution of thepaper is adaptive controller design and analysis under conditions of incompletemeasurements, incomplete control and uncertainty.
