PWM控制原理在自动控制中的应用

Application of PWM Controling Principle in Automatic Control

ＰＷＭ控制原理被广泛用于自动控制中，我们研制的“ＢＦ０７自动控制发酵罐”就是利用ＰＷＭ控制原理实现了对温度、搅拌速度、酸度、溶解氧４个参数的调控．本文给出ＰＷＭ控制原理及利用ＰＷＭ控制原理实现对温度和搅拌速度的调控．

PWM controling principle is used extensively in automatic control circuits. This paper showsd PWM controling principle and applications of the principle in the “BF07” type antomatic control fermatation pot. Using the principle both temperature and agitation speed controls are achieved
