摘　　要：为了解决一类不确定非线性系统输出反馈镇定问题,首先构造了合适的状态观测器,进而基于增加幂次积分方法和自适应技术,给出了设计光滑自适应输出反馈控制器的新方法.主要理论结果表明:所设计的控制器不仅保证闭环系统的所有状态均是有界的,而且原系统的状态和观测器的状态渐近收敛到零.The stabilizing problem was investigated for a class of uncertain nonlinear systems. First, an appropilate observer was introduced, and then based on the addition of a power integrator and adaptive technique, a new method was presented to construct a smooth adaptive output feedback controller. The main theoretical resuits show that the designed controller not only guarantees that all the states of the closed-loop systems are bounded, but also the states of the original system and the observer asymptotically converge to zero.
