本文考察其标称系统的相对阶大于1同时含匹配和非匹配不确定性的SISO非线性系统的动态输出反馈镇定问题．文中给出一个关于一类非线性系统为渐近稳定的结果．利用此结果设计出一类输出反馈动态补偿器，该补偿器可以实现对所论非线性不确定系统的动态输出反馈渐近镇定．
This paper investigates the dynamic output feedback stabilization problem of SISO nonlinear systems whose relative order is greater than 1 and whose matching and non-matching uncertainties are both nominal. In this paper, we give an asymptotic stability of a class of nonlinear systems. Using this result, a kind of output feedback dynamic compensator is designed, which can realize the dynamic output feedback asymptotic stabilization of the nonlinear uncertain system.
