| 摘 要： | 讨论可完全线性化的不同类型混沌系统之间的同步问题.根据滑模控制原理求取混沌同步控制形式,利用扩张状态观测器对系统信息进行渐进估计,把复杂的滑模控制策略变为可实现的控制方式,以此实现具有不确定性混沌系统的同步.以Duffing和Vander Pol系统为例进行仿真,效果良好.

| Abstract: | The synchronization of strictly different chaotic systems,which are fully linearizable,is discussed in this paper.A chaotic synchronizing controller is provided based on the sliding mode control design.To make the controller physically realizable,available synchronizing error is used to estimate system uncertainty,such as the structure difference or parameter mismatching,based on the extended states observer (ESO),and then this controller is used to synchronizing two continuous chaotic systems.Illustrative example of the synchronization of Duffing and Van der Pol oscillators is proposed to show the effectiveness of this method. |
