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.

关 键 词:混沌系统  参数未知  主动Backstepping方法  自适应控制

Abstract: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...
Keywords:chaotic systems  parameters unknown  active backstepping method  adaptive control
