摘　　要：“多时滞系统H_∞鲁棒控制”一文给出了多时滞系统满足H_∞性能指标的充分条件及带不确定性Riccati不等式具有鲁棒性的充要条件,并在此基础上提出了带不确定性多时滞被控对象经状态反馈后满足H_∞鲁棒设计指标的充分条件。然而该文在给出带不确定性Riccati不等式具有鲁棒性的必要性的证明中有一些关键性的错误,导致其必要性是不成立的。指出这些错误的同时,给予了相应的修改。Paper 'H∞, robust control for multi-time delay systems' proposed a method of designing H∞ state feedback controller. Furthermore, the above literature gave a necessary and sufficient condition for a Riccati inequality with parameter pertur-bances to have robustness. However, there are some serious mistakes in the proof of the literature. Here, the authors pointed out these mistakes and gave the corresponding modification. Additional, the authors discussed the uncertainties.
