摘要
主要研究了存在状态滞后的线性时变不确定时滞系统的鲁棒Ｈ∞控制分析和综合问题．给出了对所有容许不确定性，被控对象可二次镇定和满足从干扰输入到控制输出的Ｈ∞范数界约束的动态输出反馈鲁棒Ｈ∞控制分析结果．将不确定时滞系统的鲁棒Ｈ∞输出反馈控制器设计问题等价为两个线性时不变系统的状态反馈标准Ｈ∞控制问题，并由此得到反馈阵和观测阵，最终得到鲁棒Ｈ∞控制器综合设计方法．
This paper focuses on analysis and synthesis of robust H control for linear timevarying uncertain dynamic systems with delayed state.A dynamic output feedback controller is presented to quadratically stabilize the plant and reduce the effect of the disturbance input on the controlled output to a prescribed level for all admissible uncertainties.Two equivalent linear timeinvariant structural descriptions for the timevarying uncertain systems with delayed state are obtained to get the controller gain matrix and the observer gain matrix.
