摘要
结合反向同步和延迟同步,提出一种新颖的反相延迟同步,基于状态观测器构造响应系统,并利用极点配置技术得到误差系统在原点处渐近稳定,实现了反相延迟同步。用Chen’s混沌系统和Chua’s电路为例进行数值仿真,在预先设定特征值的基础上,经极点配置可得到同步的响应系统,实验结果显示该方案简单有效。
Abstract
Combining anti-synchronization with lag synchronization,a novel kind of inverse lag synchronization is proposed. Moreover,based on state observer,a response system is constructed. The error system is global asymptotically stable at the origin by using the pole placement technique,and inverse lag synchronization occurs. The Chen's system and Chua's circuit are used as illustrative examples for verification.With the preconcerted eigenvalues,the synchronized response system is obtained via the pole placement technique. Numerical simulations verify the effectiveness of the proposed method.
