This paper considers the semiglobal stabilization via output-feedback for a class of uncertain nonlinear systems. Dif- ferent from the existing results, the systems under investiga- tion possess more serious nonlinearities and unknown control coefcients which substantially increase the difculty of output- feedback controller design. Combining the backstepping method and output-feedback domination approach, a semiglobal stabi- lizing controller is explicitly given, which can guarantee that the closed-loop system achieves the semiglobal asymptotic stability under the appropriate choice of design parameter. A simula- tion example validates the theoretical results and the proposed approach.
