研究了时变时滞混沌系统的周期间歇控制指数同步问题。基于微分不等式方法和分析技巧,得到了一些新的有用的同步判据。值得注意的是,本文所用的方法不同于现有工程中所采用的技术,并且导出的条件保守性较小。特别地,本文解除了控制宽度的一个强约束,即控制宽度应大于电流参考施加的时间延迟。此外,新的同步准则不施加任何限制的时间延迟的大小。最后通过数值算例说明了理论结果的有效性。
This paper is concerned with the problem of exponential synchronization for chaotic systems with time-varying delays by using periodically intermittent control. Some new and useful synchronization criteria are obtained based on the differential inequality method and the analysis technique. It is noteworthy that the methods used in this paper are different from the techniques employed in the existing works, and the derived conditions are less conservative. Especially, a strong constraint on the control width that the control width should be large than the time delay imposed by the current references is released in this paper. Moreover, the new synchronization criteria do not impose any restriction on the size of time delay. Numerical examples are finally presented to illustrate the effectiveness of the theoretical results.
