摘要
针对一类不确定混沌系统,运用自适应滑模变结构控制方法,设计了相应的控制器和自适应律,实现了混沌系统的主从同步控制。通过构造Lyapunov函数在理论上证明了该同步方法的有效性,并且在不确定项上界未知的情况下,对系统未建模部分和噪声干扰具有很强的鲁棒性。最后以Duffing-Holmes系统为例,进行了混沌同步仿真,仿真结果表明该方法的有效性。
An adaptive sliding mode control scheme for a class chaotic system with uncertainties is proposed in this paper. The approach is not only more robust to unmodeled part and disturbances, but also does not need the upper bound of the uncertainty of chaotic system in advance .Illustrative examples of chaos synchronization for uncertain Duffing-Holmes system are presented to demonstrate performance of the controller.
