前一讲介绍了工业控制机的基本情况,后面两讲将分别讲述数字计算机用于化工、石油工业中的直接数字控制和最优控制.这一讲里,拟就有关计算机控制的原理做一个概要性介绍.(一)概述毛主席教导我们:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停此在一个水平上.因此,人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进.”化工自动化的飞速发展也生动地体现了这一英明论断.总地来说,化工生产过程自动化包含着自动检测、联锁保护和自动控制这样一些内容;从发展过程来看,大致出现了仪
The previous one introduced the basic situation of industrial control machine, the latter two talks will separately talk about the digital computer used in chemical industry, the direct digital control and optimal control in the oil industry.In this talk, it is proposed to do a theory about computer control Outline 1. Chairman Mao taught us: “In the struggle for production and within the scope of scientific experiments, mankind always develops continuously, and the nature always develops constantly, so it will never stop at a certain level. Therefore, , Mankind always have to sum up experience, discover something, invent something, create something, and make progress. ”The rapid development of chemical automation also vividly embodies this brightly stated conclusion.In general, chemical production process automation Contains automatic detection, interlock protection and automatic control of such content; from the development process, the general appearance of the instrument
