针对具有状态滞后和时变未知且有界不确定性的线性时变不确定时滞系统，研究了当状态不完全可测时的鲁棒镇定问题．利用Riccati方程方法，提出了一种基于观测器的动态输出反馈镇定控制器设计方法，并得到了不确定时滞系统可输出反馈镇定的充分条件．最后通过一数值例子来说明了所得结果的可行性．
For a class of uncertain linear systems with state delay and time-varying uncertainties and bounded uncertainties, the robust stabilization problem is investigated when the state is not completely measurable. Based on the Riccati equation method, an observer - based dynamic output feedback stabilization controller design method is presented. The sufficient conditions for the output feedback stabilization of an uncertain time - delay system are obtained. Finally, a numerical example to illustrate the feasibility of the results obtained.
