| Abstract: | The problem of global stabilization for a class of uncertain nonlinear systems using linear output feedback is considered. Instead of imposing triangular type restrictions on the nonlinear uncertainties, the existing linear output feedback control schemes were extended to certain nontriangular type restrictions. A linear high-gain observer and a coupled linear high-gain controller were constructed, and by using the gain scaling method, global stability of the closed loop system can be achieved. Simulation results are given to show the effectiveness of the proposed scheme. |
