Dynamics analysis of a novel hyperchaotic system

A new four-dimentional hyperchaotic system based on a new three-dimensinal system was built by adapting nonlinear controller.Some of its basic dynamical properties were studied briefly,such as the feature of equilibrium,the hyperchaos attractor,the bifurcation diagram and Lyapunov exponent.Numerical simulations showed that the new system's dynamics behavior can be periodic,chaotic and hyperchaotic as the parameter varies,and the system can be used in chaotic secrete communication.
