摘要
基于主动的Backstepping控制方法,通过引入自适应控制,在线辨识系统的参数,设计自适应控制器;对一类含有未知参数的混沌系统进行控制,使被控系统能够稳定到任意点.同时,基于Lyapunov稳定性理论,分析系统的稳定性.该控制方法对于具有严格参数反馈形式的系统,以及非严格参数反馈形式系统均适用.数值仿真结果验证了该控制方法的有效性,系统在控制器的作用下能快速稳定到期望点.
Based on active backstepping controlling method, the adaptive control scheme is introduced for online parameter identification and adaptive controller design. A class of chaotic systems with unknown parameters are controlled so that the controlled systems could be stable at any user-defined point. Meanwhile, the stability of the system is analyzed based on Lyapunov stability theory. The control scheme is suitable for systems in parametric strict-feedback forms as well as systems in parametric non-strict-feedback forms. The results of numerical simulation have proven the effectiveness of control method and the system with the controller can reach the desired point rapidly and stablely.
