前言目前,国内外控制机的可靠性,以及管理和生理习惯上的原因,影响了直接数字控制技术在化工过程中广泛应用。然而为什么在计算机未出故障的可靠运行中,对它的控制效果的评价也并非优于连续式调节?这就需要从化工过程控制角度出发来研究这一课题。准确地获得被调量的偏差,充分利用计算机的优点尽量采用先进的自动化系统,选择行之有效的控制规律及其算式,合理地整定调节器的参数,这些都是提高其控制效果
Preface At present, the reliability of control machines at home and abroad, as well as the management and physiological reasons, have affected the direct digital control technology widely used in chemical processes. However, why the evaluation of its control effect is not superior to the continuous adjustment in the reliable operation of the computer without failure? This needs to be studied from the chemical process control point of view. Accurately get the deviation of the amount being measured, make full use of the advantages of the computer Try to use advanced automation system, select an effective control law and its formula, and adjust the parameters of the regulator, these are to improve its control effect
