摘要: 为了研究串级 PID 调节器在 DCS 中的应用,选用一种基于 ABB-800F 软件自定义的用户功能块作为研究对象,对该软件自带 PID 通用连续调节控制块(CCU)展开 PID 调节器面板及程序设计,增强其功能,通过密码解锁,实现一种能够直观进行图形化界面参数整定及调试的通用 PID 软调节器,既可以单回路 PID 控制,又可以串级 PID 控制,且能在编程组态中像功能块FBD 指令一样使用。该用户功能块串级 PID 软调节器在某化工甲醛生产中应用,已经取得良好的效果。

Abstract: In order to study the application of cascade Pl controller in DCS, a self-defined user funetionblock based on ABB -800F software is selected as the research object, and the software comes with itsown PlD universal continuous adjustment control block(CCU), expand the PlD controller panel andprogram design , enhance its function, unlock through password. It realizes a general PlD soft regulatoiwhich can adjust and debug parameters intuitively in graphical interface. It can realize single loop Plcontrol and cascade PID control, and can be used in programming configuration like FBD instruction.'This user funetional block cascade Pll soft regulator has achieved good results through application in theproduction of formaldehyde in a chemical industry, and has the value of reference and promotion.

Key words: user function block, cascade PID controller, parameter setting
