中文摘要
      从半局镇定角度研究了一类非线性系统的输出反馈镇定问题,这类系统具有较强的非线性增长特征.利用高增益观测器,把非分离设计原则应用于输出反馈半局镇定控制器设计.在不需系统具有一个一致完全可观状态反馈控制器情况下,给出了输出反馈控制器的设计方法.对任意给定紧子集,所设计的反馈控制器使闭环系统是渐近稳定的且吸引域包含指定的紧子集.最后的仿真实例说明了设计方法的有效性.
英文摘要
      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.
