Abstract: A state feedback controller was designed by Lyapunov stability theory, and the sufficient conditions were given to the implementation of synchronization of two delayed chaotic systems via linear matrix inequality technique. Taking the delayed Chen chaotic systems and the delayed Lorenz chaotic systems as example and according to the given theorem, the linear matrix inequality is solved so as to make the two systems asymptotically synchronous. These examinations show that the designed controller is easy to implement in practice and the simulation results demonstrate the effectiveness of the presented method.
