1Introduction
Constantpressurewatersupplysystemshavebeenwidelyusedinvariousindustrialandcivilfields.Withthedevelopmentofautomationtechnology,moreandmorenewcontrolmethodsareappliedtotheconstantpressurewatersupplysystem,whichgreatlyimprovesthecontrolprecisionandstabilityofthesystem.Thedevelopmentofthebuilt-inPIDmoduleandcontrollermoduleofthefrequencyconverterprovidesanewwayforthedesignofconstantpressurewatersupplysystems.Thedesignoftheconstantpressurewatersupplysystembasedonthebuilt-inPIDmoduleandcontrollermoduleofthefrequencyconverterhastheadvantagesofhighcontrolprecision,highcontrolstability,andlowcost,whichcaneffectivelymeettheneedsofmodernsociety.
