国内制浆造纸自控及仪表的现状与发展趋势

The present situation and development trend of automation and instrument for pulping and paper-making in China

制浆造纸过程是一个复杂的工业过程,具有高度不确定性、非线性、关连性、大滞后和状态不完全性等特点,目前控制系统以现场总线为核心,正朝着整厂集中控制的方向发展,控制内容更具广泛性,控制方式更具专业化。本文分析了我国制浆造纸自控及仪表的现状和发展趋势,阐述了自动控制系统在制浆造纸生产中的重要作用,对具体的控制方式进行了探讨。

Pulping and papermaking is a complicated industrial process with high uncertainty, nonlinearity, connectiveness, big delay and incompleteness. With the fieldbus as the core, the present development trend of control system is the whole plant central-control with more extensive control contents and more specialized control methods, The paper analyses the tend of automation and instrument for pulping and papermaking in China, expounds the important functions of automation system in pulping and papermaking and probes into the specific control modes.
