Impulsive Synchronization of Chaotic Lur'e Systems by Measurement Feedback

In this paper we consider impulsive control of master-slave synchronization schemes that consist of identical Lur’e systems. Impulsive control laws are investigated which make use of linear or nonlinear dynamic measurement feedback. A sucient condition for global asymptotic stability is presented which is characterized by a set of matrix inequalities. Synchronization is proven for the error between the output signals. The method is illustrated on Chua’s circuit and a hyperchaotic system with coupled Chua’s circuits.
