摘要
基于一个新的三维自治混沌系统,通过引入非线性控制器,构造了一个新的四维超混沌系统.对该系统平衡点的性质、超混沌吸引子的相图、系统的分岔图和Lyapunov指数等基本动力学特性的分析及数值模拟结果表明,新的四维超混沌系统随着新引入参数的变化呈现周期、混沌及超混沌动力学规律,可以用于混沌保密通信.
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.
