Semiglobal stabilization for a class of feedforward nonlinear systems via output-feedback

This paper deals with the semiglobal stabilization via linear output-feedback for a class of feedforward nonlinear systems. Under weaker assumptions than those in the related literature, a linear output-feedback controller is explicitly given by output-feedback domination approach. It turns out that, with the appropriate design parameter, the designed controller can achieve the semiglobal asymptotic stability of the resulting closed-loop system. A numerical example is provided to illustrate the effectiveness of the theoretical results.
