The Design of Frequency Conversioned and Isobarically Fuzzy Control Water Supplying System Based on PLC

In this paper a frequency conversioned and isobarically water supplying control system is designed,which apply the Fuzzy control technology,it can settle the traditional PID control problems such as bad stability ,diffucult to modulate parameter. as soon as, effectively resolved the probloms that Fuzzy control is difficult to realize by PLC.This system can replace the water suppying mode of directly bring pressure by hathpace or water pump,it improve the quality of water suppying,and there is obvious effect ofenergy saving and certain of practicing and popularizingion value in it.
