A Design of Constant Pressure Water Supply Control System

摘要

This system used the simple frequency conversion method to replace the high price full-function Pu frequency which only be able to use its part of functions in the water supply system ,reduced the price of device in maximum limit, enhanced the reliability, and be convenient to maintain; Two, with the simple comparison test, carries on the constant water pressure adjusting, it is easy to realize、highly fast and stable, Don't use the traditional PID regulator, thus, needn't exactly make PID parameter.
