Abstract: Throughout this paper, the nonlinear observer-based synchronization problem for two coupled Chen chaotic systems is developed. Initially, complete synchronization conditions of coupled chaotic systems, is provided. The active control law developed is based on the use of aggregation techniques for error dynamics stability study and the arrow form matrix for systems description. Afterwards, by the design of an adequate nonlinear state observer, a new synchronization scheme is formulated for two identical chaotic systems. Numerical simulations are carried out to assess the performance and the efficiency of the proposed contributions.
Keywords: Aggregation Techniques, Arrow Form Matrix, Chaotic Systems, State Observer, Synchronization.
