摘要
根据一类混沌系统的结构和Lyapunov稳定性理论,讨论一类混沌系统在有参数和外部扰动情况下的同步问题.在驱动系统参数已知和未知两种不同的情况下,分别设计了适当的控制器以及参数自适应律实现了一类混沌系统的同步.以Arneodo系统为例进行了数值仿真,结果表明这些控制器及参数自适应律是有效的和可行的.
This paper, according to the structure of a class of chaos system and Lyapunov stability theory, has discussed the synchronization of these chaos systems under disturbances. When the parameters of drive system are known or unknown, appropriate controllers and control laws are designed to realize the synchronization of a class of chaos systems, with Arneodo system as the example of simulation. The research results have proved that these controllers and adaptive laws of parameters are effective and feasible.
