Abstract
This paper derives a measure of dynamic control quality within the Taguchi framework (G. Taguchi, E.A. Elsayed, T. Hsiang, Quality Engineering in Production Systems, McGraw-Hill, New York, 1989) which estimates product quality (in economic terms) by the losses incurred when specified product characteristics depart from their nominal values. In this sense, a control system may beviewedasa‘‘product’’withstabilityandperformancepropertiesasitsrequiredcharacteristics.Thedegreetowhichsystem inputs and outputs depart from their nominal values is used to give an estimate of stability and performance quality, respectively. Displaying control quality graphically with stability and performance qualities as the two axes can be used to highlight the trade-o betweenthesetwo characteristics.Thistechniquewasusedtoevaluatethequalityoeredbyfourmodel-basedcontrollersona distillation column model responding to a typical disturbance, and how the presence of measurement and valve dynamics aected control quality. It is anticipated that the measures derived in this paper (being both time-based and economic) may prove useful in conveying control quality in a common language understood by engineers, operators and management. 2000 Elsevier Science

回复 3# krin 的帖子
呵呵，是啊是啊，我是用工具翻译的，没怎么动脑袋。一定积极参加对这篇文章的讨论:handshake 谢谢各位好心人士的提醒了,其实我有翻译的,可是翻得太烂了,不好意思拿出来~~~~ 我先自己看下,到时再请教各位大侠~~ ddddddddddd 2# 梦回书香
是啊，这样长篇大论不太好啊！ 可以帮你翻译，发到我油箱 连文本都没怎么整理，就让别人翻译，没诚意，鄙视
