Abstract:This paper put forward a kind of stable pressure water supplying system based on fuzzy control theory ,and designs a fuzzy controller of adjusting the factor by oneself ,which solves the problem that the parameter is difficult to adjust in the course of the traditional PID control. This scheme achieves the water supply with constant pressure .It introduces the configuration and function of the system, and gives a simulation analysis to the system.The results prove that the water supply system based on fuzzy control is better to make the water pressure constant.
Key words:Fuzzy Control Variable frequency drives Supply water under stable pressure
