摘要
针对一类特定结构的含有未知参数的混沌系统,给出了一种基于状态观测器的自适应同步控制方法。通过一个带有控制器的非线性状态观测器实现混沌系统的渐进同步并对未知参数进行估计。该控制方法简单易行,且能通过自适应律自动调整以跟随参数的变化,具有较强的鲁棒性。理论分析和仿真实验都证明了该方法的有效性。
The synchronization problem of a class of chaotic systems with unknown parameters is discussed in this paper. An adaptive observer - based scheme is constructed to realize asymptotical synchronization and estimate the unknown parameters. With this method, system can adjust itself to the variation of parameters via adaptive laws. It is simple, feasibily and robust. Theory analysis and the simulation results have verified the efficiency of the proposed scheme.
