摘要
对一个新混沌系统,先分析其稳定性,再通过坐标变换对此系统进行控制。接着设计了一自适应控制器,通过自动调整参数β,实现了与另一系统的异结构同步,并把此控制器运用到保密通讯中。理论分析和数值计算的结果完全一致,表明了该方法的有效性。
The stability of a new chaotic system is analyzed so as to control the system with linear feedback method through the coordinate transformation. An adaptive controller is designed to realize the chaos synchronization between the two different systems. Through the automatic adjustment of the parameter β, the chaos synchronization with another system is realized. Then the controller is applied to the secret communication. Results from theoretical analysis accord with that from numerical calculation. The effectiveness is proved.
