可编程序控制器中PID控制的研究

阐述了在闭环自动控制系统中PID的重要性和必要性,并介绍了可编程序控制器中“PID”的控制方式、PID的算法、数字滤波、不完全微PID、反馈量微分PID算法以及PID的计算公式;同时研究了在可编程序控制中PID是如何控制的,采取何种方法和措施,较详细地介绍了用户在可编程序控制器中如何使用PID功能指令,使用传送指令如何设定初始参数,以及它们数据寄存器的编号与存放地址,从理论到实践分析和总结了这方面的经验,为可编程序控制器中对PID控制的进一步研究和应用准备了基础。

The Study of PID Control for the PLC

This paper states the essences and necessities of PID control in the closed automatic control system and explores the PID control tactics algorithm, digital filter, uncompleted differential PID, feedback signal differential PID algorithm, as well as calculation formula of PID and explores ways and the means what PID control for the Programmable Logic Controller. In some detail telling about how we user of PLC make use of PID function instruction and how set up the initial data by the move instruction , as well as the data register number and its address of memory. The experience analyzed and summarized from theory to practice lays a foundation for the continued research of PID.
