Abstract: The chaotic synchronization control with diverse structures and uncertain parameters is studied based on a new continuous autonomic chaotic system. A nonlinear controller is presented based on Lyapunov stability theory, which insures the stability of chaotic synchronization. According to the strategy of adaptive control for parameters, the uncertain parameters of systems are estimated. The good chaos synchronization between the new chaotic system and the Lorenz chaotic system has been proved theoretically when the parameters are fully unknown. The unknown parameters are identified. Numerical simulations show the effectiveness of the proposed method.
