SYNCHRONIZATION BY OBSERVER BASED APPROACH FOR A CLASS OF NONLINEAR CHAOTIC SYSTEMS

In this paper, we present a new approach based observers for the synchronization of a large class of chaotic systems. Thanks to the Lyapunov theory we give new sufficient synthesis conditions for the synchronization problem. These conditions are formulated as Linear Matrix Inequalities (LMIs) which are easily tractable using standards optimization algorithms. Numerical examples are provided to show high performances of the proposed approach and the large class of chaotic systems that are concerned.
