摘要
本文研究一类不可观非线性系统的动态输出反馈镇定 .基于逼近渐近稳定性的概念 ,给出了动态输出反馈可镇定的充分条件 .本文主要结果的直接推论是零动态逼近渐近稳定的最小相位系统能用动态输出反馈镇定 .
This paper deals with the problem of stabilization of a class of nonlinear systems with linearly unobservable modes by dynamic output feedback. Based on the concept of the stability in approximation, sufficient conditions for dynamic output feedback stabilizability are obtained. An immediate consequence of our result is that if a nonlinear system has relative degree and its zero dynamics is asymptotically stable in approximation, then it can be stabilized by dynamic output feedback. Our main result may handle some non minimum phase nonlinear systems.
