4 h5 ?! L1 Y) r, T" u3 G2 n   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 be  viewed  as  a  ‘‘product’’  with  stability  and  performance  properties  as  its  required  characteristics.  The  degree  to  which  system 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 between  these  two characteristics.  This  technique  was  used  to  evaluate  the  quality  oered  by  four  model-based  controllers  on  a 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

讓別人全文翻譯的行為不太贊同哦，如果中間有些句子拿捏不準(zhǔn)可以提出來大家討論，這樣對自己對大家才有提高嘛

呵呵，是啊是啊，我是用工具翻譯的，沒怎么動腦袋。
一定積極參加對這篇文章的討論
