一、前言 S系列J型过程控制仪表中有固定程序PID控制器、可编程PID控制器、自整定PID控制器等。这里着重介绍STGJ-1002型固定程序PID控制器。 STGJ-1002型固定程序PID控制器有各种附加功能和某些内部结构变化供用户选择。这里以某厂产品为例,其识别方法如下: 型号识别号主要功能附加功能STGJ-1002 -0000 PID开方、前馈STGJ-1002 -1000 PID开方、前馈、非线性、比值偏差平方STGJ-1002 -2000 PID开方、前馈、串级STGJ-1002 -3000 PID用户特殊算法识别号含意如下:
I. Introduction S Series J-type process control instruments in a fixed program PID controller, programmable PID controller, self-tuning PID controller. Here focuses on STGJ-1002 type fixed program PID controller. STGJ-1002 fixed program PID controller has various additional functions and some internal structure changes for the user to choose. Take a factory product as an example, its identification method is as follows: Model ID Main Functions Additional Functions STGJ-1002 -0000 PID Square, Feedforward STGJ-1002 -1000 PID Square Root, Feedforward, Nonlinear, Deviation Square of Difference STGJ -1002 -2000 PID square root, feedforward, cascade STGJ-1002 -3000 PID user special algorithm ID means the following:
