摘　　要：该文提出了一种基于Chen系统的新型三维指数混沌系统。重点分析了系统参数对整个混沌系统的影响,给出了混沌系统吸引子图,Lyapunov指数图,分叉图等。最后利用DSP实现了该混沌系统,并对由系统生成的数字序列做了NIST测试,测试结果表明序列性能良好。A new chaotic system with an exponent term which is based on the Chen chaotic system is proposed.The influence of system parameter on the chaotic system is discussed.This paper also shows the attractor graph,Lyapunov exponent spectrum,bifurcation diagram and so on.The chaotic system is implemented by using DSP.In addition,performance of the sequence which is generated by the system is measured by NIST test.The results show that the performances of the sequences are good.
