摘　　要：本文研究一类不确定非线性平面系统的输出反馈镇定问题,在该系统的线性化不可测的情况下,通过选择适当的观测器和改进加幂积分器的方法,设计输出反馈控制器,使闭环系统全局有限时间内输出镇定。The problem of Output-feedback Global stabilization for a class of uncertain nonlinear systems was studied. In the case of the unobservable systems, the appropriate observer was selected and adding-a-power inte- grator was improved. And an output- feedback controller was designed so that the closed-loop systems is global stable in finite time.

关 键 词：不确定非线性 输出反馈 有限时间镇定 全局镇定
