摘要
本文运用理论分析及数值仿真的方法,分析了一类含非线性负电容的四阶自治超混沌系统的鲁棒性。重点研究了噪声干扰及参数扰动情况下超混沌系统的耦合同步问题,定量分析结果表明,经过结构简单易于实现的线性耦合控制器,四阶自治超混沌系统可以实现较为稳定耦合控制同步,并且超混沌同步系统对于噪声干扰及参数扰动具有较强的抑制能力,耦合控制超混沌同步系统具有较好的鲁棒性。
In this paper, Research on the analysis of robust ability for a kind of hyper-chaos system combined theory analysis with numerical simulation is carried out. The key problem researched could be the property of robustness owned by coupled-control and synchronization system. The researching results illustrated that the stable controlling on the autonomous-circuit hyper-chaos system could be arrived under the condition of linear couple controller with simple structure, and the characterization of resisting noise and parameter changing or robustness could be owned by the algorithm of synchronization of hyper-chaos.
