以一类参数不确定Rossler系统为例,研究了自适应混沌控制器的设计方法。首先基于自适应反推控制思想,对单个控制器进行了设计;其次基于Lyapunov函数,对2个控制器进行了设计。数值分析结果表明2种设计方法均能有效地对系统参数未知的混沌系统进行控制。
Taking a class of uncertain parameters Rossler system for example, the design method of adaptive chaos controller is investigated. Firstly, based on adaptive backstepping algorithm, single controller is designed. Secondly, due to Lyapunov func- tion, two controllers are designed. Validity of two different methods is verified numerically for controlling uncertain parameters systems.
