Decentralized Output Feedback Semiglobal Stabilization for a class of Large-Scale Nonlinear Systems

In this paper, the problem of decentralized semi-global stabilization via output feedback for a class of large-scale nonlinear systems is studied. The systems addressed allow not only nonlinear interconnections but also nonlinear growth with unmeasurable states, which are not able to be stabilized by output feedback compensator in global sense. Based on high-gain observer, decentralized output feedback controllers are presented, which achieves semiglobal asymptotic stabilization of the large-scale nonlinear systems
