本文给出一个新的定义 :纯时滞系统总体满意控制 ,即该系统不仅对跟踪设定的控制信号 r(t)应有快速平稳的优化性能指标 ,而且对负荷扰动 d(t)和参数扰动都有满意的强壮性 .文中讨论怎样应用背驰定律来实现这一目标 ,给出几个算例 ,并和最新进展进行比较研究 .结果表明 ,其总体性能指标比各种改进型的Smith预估器控制系统好 ,特别适用于不确定时滞系统 . In this paper, we give a new definition: the overall satisfaction control of pure time-delay system, that is, the system not only has a fast and smooth optimization performance index for the tracking control signal r (t) Perturbation has a satisfactory robustness.This paper discusses how to use the divergence law to achieve this goal, gives a few examples, and with the latest progress of the comparative study.The results show that the overall performance index than the improved Smith Predictor control system is good, especially for uncertain time-delay system.
