在大庆石油输送检测过程的自动控制系统中，被控制过程总具有不同程度的时滞，其纯时滞地（hz）体现了控制任务的难度“’，特别在鲁棒性分析中出现时滞的不确定性导致分析的困难，本文即是针对这一问题而考虑的。关于一阶时滞线性系统的全时滞的稳定性在文献“’中给出了充分
In the automatic control system of Daqing petroleum transportation testing process, the controlled process always has different degrees of time lag, and its pure time lag (hz) reflects the difficulty of control tasks. “Especially in the robust analysis, time lag The uncertainty of this paper leads to the analysis of the problem, this article is to consider for this problem.For the first-order delay system, the stability of the full time delay given in the literature ”
