数字化控制系统基本技术分析

The Basic Technology Analysis on the Digitized Control System

就数字化控制系统的基本技术做了一个学理上的分析。在此基础上,深入探讨了数字化控制系统的采样周期问题和核能系统数字化PID控制策略问题,给出了采样周期的选择原则,给出了离散化原理的广泛存在性实例,指出了PID的积分饱和问题所在并提供了改进途径。这里特别强调指出,数字化技术既是计算机和信息化时代的核心技术,也是核电站和未来智能化时代重要的基本技术。

This paper gives the analysis on the basic technology of the digitized control system academically. Based on this, the further discusses are provided here, which concern with the sample time problem and the digitized PID control scheme problem. The detailed contents are as follows：The selection principle of the sample time is given. The examples of the discrete principle existed widely in the sur- rounding are given. The problem of PID Reset windup is pointed out, and the relative improvement access is provided as reference. It is needed to emphasize that the digitized technology is the key technology in the computer and information times, also is the important basic technology for nuclear power plants and the future artificial intelligence times.
