| 摘 要： | 对具有外部扰动的统一混沌系统,讨论了一种混合同步设计方法;首先对响应系统进行构造,使响应系统的一个状态方程与驱动系统具有相同的结构,另两个状态方程是驱动系统的部分状态观测器,其次通过极点配置方法,实现两个混沌系统的状态渐进同步,并给出了数值仿真,然后,利用初值敏感的统一混沌序列对图象象素进行加密解密;理论分析和数值仿真验证了该方法的有效性和可行性。

| Abstract: | A design method of combined synchronization for unified chaotic system in the presence of perturbation is discussed.First,we construct the responser system so as to make a state equation of responser system share one of same structure with driver system,and the other two state equations is partial state observer of driver system.Then by pole of assignment,the states of two chaotic sytem is asymptotically synchronized.Then,numerical simulation is given.Forther,encryt and decryt image pixels using unified chaotic systems with sensitive initial values.Theoretical analysis and simulation results show that the design method has good performance. |
