摘要
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 .
A time delay system which should be with good responses not only for the reference signal , but also for uncertain parameters and load disturbances is defined as global satisfying control system (GSCS). We discusse how to realize this purpose by a law of run in the opposite direction, give some examples, and make a contrast analyses with the last development for all kinds of improved Smith predictor. The results shown that the performances of the GSCS are much better than the ones of improved Smith predictor. Especially, it has special value for the uncertain time delay system.
