Wu, Zhaojing, Xie, Xuejun and Shi, Peng (2008) Robust adaptive output-feedback control for nonlinear systems with output unmodeled dynamics. International Journal of Robust and Nonlinear Control, 18 (11). pp. 1162-1187. ISSN 1049-8923
Abstract
In this paper, for a class of uncertain nonlinear systems in the presence of inverse dynamics, output unmodeled dynamics and nonlinear uncertainties, a robust adaptive output-feedback controller design is proposed by combining small-gain theorem, changing supply function techniques with backstepping methods. It is shown that all the signals of the closed-loop system are uniformly bounded in biased case, and the output can be regulated to a small neighborhood of the origin in unbiased case. Furthermore, under some additional assumptions, an asymptotical result is obtained.
