控制回路： 

     通常是针对模拟量的控制来说，一个控制器根据一个输入量，按照一定的规则和算法来决定一个输出量，这样，输入和输出就形成一个控制回路。控制回路有开环和闭环的区别。开环控制回路，指输出是根据一个参考量而定，输入和输出量没有直接的关系。而闭环回路则将控制回路的输出再反馈回来作为回路的输入，与该量的设定值或应该的输出值作比较。闭环回路控制又叫反馈控制，是控制系统中最常见的控制方式。下面介绍几种常规的反馈控制的模式

 

I/O点： 

在自动化控制系统中，I/O点是最经常听到的一个术语。它是指输入/输出点，I代表INPUT，指输入，O代表OUTPUT，指输出。输入/输出都是针对控制系统而言，输入指从仪表进入控制系统的测量参数，输出指从控制系统输出到执行机构的参量，一个参量叫做一个点。一个控制系统的规模有时按照它最大能够控制的I/O点的数量来定的。
