Parameter Identification of a New Hyper-chaotic System

In order to make better use of parameter identification to enhance the security of communication system, this paper focuses on the parameter identification of a new four-dimensional autonomous hyper-chaotic system. The nonlinear dynamical behavior of the system is investigated further. Moreover, the suitable parameter identification observers are designed for the new hyper-chaotic system with fully unknown parameters. Numerical simulations show that the effectiveness and feasibility of the identification observes to identify the parameters.
