摘　　要：　在分析板纸机控制难点的基础上,提出一套新的以SiemensS7 300PLC为核心的定量水分DCS。该DCS包括绝干浆量控制子系统、扫描架控制子系统、定量水分(B/M)控制子系统和三段供气子系统,采用了自整定PID/PI控制、比值控制和前馈解耦控制等多种高级过程控制算法。本系统在山东某公司的三叠长网板纸机上投运成功。After the analysis of the intractable points to control board-paper machine,a novel quality control system(QCS) is proposed based on Siemens S7-300 PLC.The QCS consists of pulp base dry control sub-system,scanner control sub-system,basis weight moisture control sub-system and three-section steam supply sub-system.Several advanced process control algorithms such as self-tuning PID/PI,ratio control and feedforward control are adopted.It has been in operation on a three-layered fourdrinier paper-board machine in a company of Shandong.
