一类非线性MIMO不确定系统的动态输出反馈镇定

DYNAMIC OUTPUT FEEDBACK STABILIZATION FOR A CLASS OF NONLINEAR UNCERTAIN SYSTEMS

考察其标称系统的相对阶大于｛１，１，…，１｝同时含匹配和非匹配不确定性的ＭＩＭＯ非线性系统的动态输出反馈镇定问题．文中直接用Ｌｙａｕｎｏｖ方法构造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 studies the dynamic output feedback stabilization problem for a calss of MIMO nonlinear systems, whose nominal system's vector relative degree>{1,1,…,1}and which contains matching and dismatching uncertainties. A kind of dynamic compensator by Lyapunov method is designed derectly, which realizes dynamic output feedback stabilization of non linear uncertain systems.
