摘要
研究了超混沌吕系统的滞后投影同步与系统参数识别.在响应系统中加入适当的非线性控制器,利用Lyapunov稳定性方法和Barbalat引理进行理论分析证明,实现了驱动响应系统之间所有变量的全局滞后投影同步,并能够对超吕系统的未知参数进行识别.最后通过数值仿真对本文中提出的理论方法的正确性及可行性进行验证.
This paper researched the Projectively lag synchronization and unknown parameters identification of hyperchaotic Lü system. Projection lag synchronization is realized between the driver and response system by adding appropriate nonlinear controller into response system and applyling Lyapunov stability method and Barbalat lemma. And the unknown parameters of hyperchaotic Lü system also can be identified. Finally, several numerical simulations were given to test and verify the correctness and feasibility of the methods proposed.
