摘要
研究了存在外界扰动情况下一类混沌系统的同步问题 ,混沌系统非线性项无需满足输出反馈形式 .首先对系统进行变换得到未受扰降价混沌系统 ,然后基于非线性观测器的思想构造同步观测系统实现了混沌同步 ,通过仿真证实了该方法的有效性 .
Synchronization problem in the presence of perturbation is considered, and the nolinear part of the chaotic system is nt in output feedback form. In this paper, we first transfer the system and obtain a nonfull order system. Second, we construct a synchronous system based on the nonlinear observer idea and realize the synchronization. Finally numerical example is illustrated and the simulation results verify the conclusion of this paper.
