The Design of Variable Frequency and Constant Pressure Water Supply System Based on Fuzzy Control

Abstract

This article starts from energy saving and improving energy efficiency, analyzes the characteristics of the pump and collects the pipe network pressure periodically by the pressure sensor, and then we can get the differential pressure signal and send it into fuzzy controller after comparing the pipe network pressure with the set pressure. After a series of fuzzy arithmetic and solution of fuzzy arithmetic, the fuzzy controller sends a precise control into the PID regulator to control output frequency of the frequency converter, so as to achieve the purpose of pump speed controlling and energy-saving.
