一种数字PID控制算法分析

Analysis of Digital PID Control Algorithm

分析了数字PID控制算法,并论述了其程序实现方法。数字PID控制算法不是简单的把模拟PID控制规律数字化,而是进一步与CPU的逻辑判断功能结合,使PID控制更加灵活,更能满足生产过程。

This paper analyzes a digital PID control algorithm, and discusses its procedure to carry out this method. The digital PID control algorithm isn＇ t to turn PID control regulation numeral, hut further combines the logic judging function of CPU,which makes the PID control more vivid to satisfy a production line.
