摘　　要：研究了一种基于Lorenz超混沌系统渐近同步的保密通信系统设计方法。首先采用T-S模糊模型对Lorenz超混沌系统进行精确描述,进而基于模糊混沌同步理论,利用Lorenz超混沌系统设计信号发射器和接收器,实现混沌保密通信。最后利用Matlab软件进行仿真研究。A novel secure communication system design method based on the asymptotic synchronization of Lorenz hyperchaotic system is investigated.First,the exact T-S fuzzy model of Lorenz hyperchaotic system is constructed.Then,based on the theory of fuzzy asymptotic chaotic synchronization,the chaotic secure communication is realized,whose signal transmitter and receiver are designed on the basis of Lorenz hyperchaotic system.Finally,simulation study is carried out by Matlab software.
