基于Backstepping方法对不确定性Chen系统的自适应控制

Adaptive Control of Uncertain Chen System Based on Backstepping Approach

基于Backstepping方法对含不确定性Chen混沌系统进行控制。当非线性Chen系统含有三个关键参数未知时,通过利用该系统的特殊性质,运用自适应控制器的设计方法,构造恰当的控制器,从而使闭环系统消除混沌并最终达到全局稳定。仿真结果验证了该方法的有效性。

With the control of uncertain Chen system using backstepping approach is concerned. When the system contains three key parameters unknown, the proper controller can obtain by exploiting the property of Chen system and using adaptive backstepping approach. The closed-loop system can be eliminated chaos and is finally stable globally. Simulation studies are conducted to show the effectiveness of the approach.
