对于一些复杂调节系统,人们往往考虑用较复杂的线路,或用较多的仪表,甚至用电子计算机去实现,虽然用它们可以解决复杂调节的问题,然而在一般情况下往往成本高、维修比较困难,若用的仪表过多,还影响到系统的可靠性。考虑到这一系列的问题,通常就用少量的仪表组成简单的调节系统,但是自动化的效果却会受到影响,有时甚至无法进行自动控制。那么能否用目前我国大量生产的为人们所熟悉的常规仪表与极少量的元器件配合后来解决一些非常规控制的问题呢?可以的。根据自动化工作的实际需要,笔者曾在这方面作了一些尝试,并取得了一定的效果。今介绍两例,以便开阔思路,扩大常规仪表的应用场合,从而取得更
For some complex control systems, people often consider the use of more complex lines, or with more instruments, even using electronic computers to achieve, although they can be used to solve the problem of complex regulation, but in general, often costly, maintenance comparison Difficult, if too many instruments, but also affect the reliability of the system. Considering this series of problems, usually a small amount of instruments to form a simple adjustment system, but the effect of automation will be affected, and sometimes can not even automatic control. So can we use the current mass production in China for the people are familiar with the conventional instruments and a small amount of components with later to solve some uncontrolled problems? Yes. According to the actual needs of automation, I have made some attempts in this regard, and achieved some results. Two cases are introduced today to broaden our thinking and expand the application of conventional instruments so as to achieve even more
