直接跟踪参考信号的自适应控制(Ⅱ)

Adaptive Control for Tracking ReferenceSignal Directly (Ⅱ)

本文是文的续篇,研究的对象是连续时间线性系统,对于系统相对阶n≥2的情况,设计出不含微分环节的自适应控制器,并证明所构成的闭环系统是全局稳定的,其输出渐近地跟踪直接给定的参考信号。

As the sequel of the paper [1], the adaptive centrol problem of continuous-time linear systems with the relative degrees n~*≥2 is considered, For such a case,differentiator-free adaptive controller is defigned. Moreover, it is proved that thestructured closed-loop systems are globally stable and that the output asymptoti-cally tracks directly a given reference signal.
