摘　　要：在分析板纸机控制难点的基础上,提出了一套新的以SiemensS7-300PLC为核心的集散控制系统。该系统包括绝干浆量控制、扫描架控制、定量水分(B/M)控制和3段供气等子系统,采用了自整定PID/PI控制、比值控制和前馈解耦控制等多种过程控制算法。系统在山东某公司的牛卡纸机上投运成功,经济效益明显。According to an analysis of the intractable points to control a board-paper machine, the paper proposes a novel distributed control sysytem（DCS）based on the Siemens S7-300 PLCs, which consists of several subsystems, such as a pulp base-dry contral system, scanner control system， B/M control system and threesection steam supply system, several kinds of advanced process control algorithm, such as selftuning PID/PI, ratio control and feedforward control, are used in it. The system has been put into use with a craft paper machine in Shandong, yielding very good economic benefit。
