Application of Fuzzy Control in Constant Pressure Water Supply System Transformation

Since the water supply system is a nonlinear and time-lag system,the conventional PID control system can not provide good water supply quality.This paper introduces a kind of design of constant pressure water supply system based on fuzzy-PID control.The system uses fuzzy control technology to transform the traditional PID control and constant pressure water supply system.This design makes the control system overcome nonlinear and time-lag problems better in the water supply system and get good transient response and steady state accuracy.During nearly half a year of commissioning,the system runs in good condition and improves water supply quality significantly.
