Synchronization of Identical Chaotic Systems Using New State Observers Strategy

Throughout this paper, the nonlinear observerbasedsynchronization problem for two coupled Chen chaoticsystems is developed. Initially, complete synchronizationconditions of coupled chaotic systems, is provided. The activecontrol law developed is based on the use of aggregationtechniques for error dynamics stability study and the arrow formmatrix for systems description. Afterwards, by the design of anadequate nonlinear state observer, a new synchronization schemeis formulated for two identical chaotic systems. Numericalsimulations are carried out to assess the performance and theefficiency of the proposed contributions.
