| Abstract: | The function projective synchronization of a new four-dimensional hyper-chaotic system is studied. Based on the stability of Lyapunov theory, we designed an effective nonlinear controller which realize the function projective synchronization of the hyperchaotic system. At the same time, we designed parameter rules which realize the identification of unknown parameters. Theory analysis and numerical simulations show that the method is effective. |
