中文摘要：

研究带变时滞耦合混沌系统的周期间歇控制滞后同步的问题。由于耦合系统之间参数不匹配,基于Lyapunov函数方法和数学分析的技巧,推导了一些准同步的准则。结果显示,同步的准则依赖于控制宽度与控制周期的比率,而不只是控制宽度或者控制周期。

英文摘要：

In this paper, we study the lag synchronization of coupled chaotic systems with time-varying delays via intermittent control. In virtue of the presence of parameter mismatch, base on the Lyapunov function method and the mathematical analysis technique, we derive some useful quasisynchronization criteria. At last, the results shows that the synchronization criteria depend on the ratio of control width to control period, but not the control width or the control period.
