“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永运不会停止在一个水平上。”前面介绍的单参数单回路调节系统解决了大量的定值调节问题,是最基本和使用最广泛的一种形式。但是由于生产的发展,工艺的革新,对操作条件的要求更加严格,参数间的相互 “In the struggle for production and within the scope of scientific experiments, human beings are always evolving and nature is constantly evolving, and forever will not stop at a level.” The single-parameter single-loop regulation system described above solved a large number of problems Value adjustment is the most basic and most widely used form. However, due to the development of production, technological innovation, the operating conditions of the more stringent requirements, the mutual
