高楼恒压供水电气传动及控制系统

Electrical Drive and Control System Used in Constant Pressure Water Supply in High Building

对高楼供水电气传动系统方案及ＰＬＣ变频调速控制技术作了分析；介绍了模糊控制技术的应用，并对ＰＩＤ控制、Ｆｕｚｚｙ控制及Ｆｕｚｚｙ－ＰＩＤ控制应用于高楼恒压供水的优缺点作了比较。运行结果表明：采用Ｆｕｚｚｙ控制及Ｆｕｚｚｙ－ＰＩＤ复合控制均能取得良好的控制效果，而后者更优于前者。

This paper analyses the plan of electrical drive system for water supply in high building and a PLC controlled converter speed drive,introduces the application of fuzzy control technology,and compares the advantages and disadvantages of PID control,fuzzy control,and fuzzy PID control.The practice proved that both fuzzy control and fuzzy PID compound control have good control effects and the latter is superior.
