基于T-S模型的混沌保密通信系统设计

Design of chaotic secure communication system based on T-S fuzzy model

基于T-S模型讨论了混沌系统的鲁棒同步问题,模糊控制器对于混沌系统本身受到的外界扰动具有一定的鲁棒性能,并将该方法应用于基于混沌同步的保密通信系统设计,实现了对数字图像的保密通信。通过对离散Henon混沌系统的仿真,证实了该方法的有效性。

In this paper, based on T-S fuzzy model, we discuss the robust synchronization problem of chaotic systems. The fuzzy controller has H^＊ performance when the chaotic system is under the external noise. This method is used for secure communication based on chaotic synchronization to realize digital image secure communication. The computer simulation on discrete Henon chaotic system has given the availability of this method.
