在第一章中,对一个闭环调节系统已作了初步分析,并了解了各环节对调节系统的动态影响。但是当我们要实现一项生产过程的自控任务时,所面临的第一件工作,将是如何根据工艺的要求,为达到产品的指标选择最好的系统方案。由于一个较复杂的过程,它的自控方案往往不止一个。怎样去判别它的好坏呢?因此就提出了调节方案如何设计的课题。所以怎样根据系统分析的基础知识,来 In the first chapter, a closed-loop control system has been initially analyzed, and understand the various aspects of the regulation of the dynamic system. But when we want to achieve a production process of the task of self-control, the first task we will face is how to choose the best system solution to meet the requirements of the product according to the technical requirements. Due to a more complex process, it often has more than one self-control program. How to judge whether it is good or bad? Therefore, the issue of how to design a regulation program is put forward. So based on the basics of system analysis, come
