多输出控制系统和分程控制系统都是以多个执行器控制一个被调量,即以一个调节器控制几个执行器的系统.这两种控制系统的构成、原理及用途有所不同,各具特点.一、多输出控制系统1.问题的提出在某些工艺过程中,基于下述原因常采用几台容量较小的相同设备来代替一台大容量的设备:(1)提高系统的可靠性.如发电 Multi-output control system and split-range control system are controlled by a number of actuators to be adjusted, that is, a regulator to control several actuators system.The two control system composition, principle and purpose are different, Each with its own characteristics I. Multi-output control system 1. Proposed problems In some processes, several smaller devices of the same capacity are often used instead of a large-capacity device because of the following reasons: (1) Reliability
