摘要
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．
This paper is focused on the problem of robustly stabilizing linear uncertain time-de-lay systems when the full states can not be measured. The systems under consideration are linearsystems with time-varying unknown-but-bounded uncertainty and delayed state. An observerbased dynamic output feedback controller is presented to quadratically stabilize the system. A sufficient condition for the robust output feedback stabilizability of the system is derived based on Riccati equation approach and the control law can be constructed by solving two algebraic Riccatiequations. Finally,a numerical example is presented to illutrate the obtained results.
