Semiglobal robust stabilization for a class of nonlinear systems with dynamic output feedbac
一类非线性系统的输出反馈半局鲁棒镇定

The problem of semiglobal robust stabilization via output feedback for a class of nonlinear systems with nonlinear growth is addressed.Based on high-gain observer,the nonseparation principle was applied to the design of semiglobally stabilizing output feedback.A procedure for explicitly constructing dynamic output controllers was presented without assumping that the systems had a uniformly completely observable state feedback.For any given compact, the resulting output compensators make the closed-loop system asymptotically stable at equilibrium origin with the basin of attraction containing the given compact set.Finally,a simulation showed the effectiveness of the result.
