一、前言关于过程控制系统,传统的看法是首先强调动态,其次才谈静态,而且把静态看做动态的特例,研究的方法与步骤也习惯从动态到静态。但是,从事生产过程工艺研究的工作者,却首先强调静(稳)态,以静态为主,动态为辅,甚至不考虑动态。自动控制工作者,一般地认为只研究过程静态不研究动态,显得太粗略。但是,一旦遇到复杂生产过程,见到过程机理模型又嫌太复杂,静态优化已难寻求,动态优化更难实现, First, the preamble On the process control system, the traditional view is to emphasize the dynamic first, then talk about static, and the static as a special case of the dynamics of research methods and steps are also accustomed from dynamic to static. However, workers engaged in the process of production process, but first emphasis on static (static) state, mainly static, dynamic supplement, even without considering the dynamics. Autocontrol workers, generally considered only research process static do not study the dynamics, is too rough. However, once encountered in complex production process, to see the process mechanism model is too complicated, static optimization has been hard to find, dynamic optimization more difficult to achieve,
