ADAPTIVE SYNCHRONIZATION OF NETWORKSWITH BOUNDED DISTURBANCES OR DELAYS UNDER INCOMPLETENESS OF MEASUREMENT AND CONTROL

An adaptive master-slave output feedback synchro-nization problem is investigated firstly for a network of interconnected nonlinear dynamical systems with de-layed couplings and then for a network of systems with bounded disturbance. The proposed structure of decen-tralized controller and adaptation algorithms in both cases is based on the speed-gradient method and pas-sivity. Conditions of synchronization for systems with delayed couplings are established. The problem of con-vergence with preliminarily specified accuracy is stud-ied for the networks of dynamical systems with dis-turbances. The effectiveness of the obtained results is demonstrated on the network of Chua systems. Key word
