摘要
对陈氏混沌系统的同步问题进行了理论分析 ,并证明了线性反馈控制同步规则。基于Lyapunov函数提出了几种基于部分变量的非线性反馈控制同步规则 ,其特点是仅需对响应系统部分变量施加控制就可以实现同步 ,而且同步速度较快。仿真结果证实了几种同步规则的可行性。通过与已有控制方法的比较 ,验证了同步响应速度快的特点。
In this paper the synchronization problem of Chen's chaotic system is studied. The linear feedback control rule for the synchronization is presented. Nonlinear feedback control rules via some variables are derived based on Lyapunov functions. The most important features are that the synchronization is achieved through the control of some variables and the speed is high. Simulation results show the feasibility of these rules. The comparisons between these control rules and other developed control methods show that the synchronization response is fast.
