Stability of Nonlinear Systems with Mismatched Uncertainties via Linear Dynamic Output Feedback
-
摘要: 研究了带有非匹配不确定性的SISO及MIMO仿射和非仿射非线性系统的动态 输出反馈镇定问题,在仅要求标称系统为双曲极小相位,以及在对系统不确定部分做较弱限 制下,分别为所论系统构造出了输出反馈形式的动态补偿器,它们均使相应的闭环系统为 Lyapunov意义下的渐近稳定.所构造的补偿器为线性的,结构简单,易于实现.

Abstract: The problems of asymptotic stabilization based on dynamic output feedback for SISO/MIMO nonlinear systems with matched and mismatched uncertainties are studied in this paper. Under only some weak constraints for the nominal systems and for the uncertainties, some dynamic output feedback compensators are constructed, which make the corresponding closed-loop systems asymptotically stable in the Lyapunov's sence. -
