Hi,
I am about to start tuning a PID loop for a refrigerant system using PIDE function in Allen Bradley Studio 5000 Logix Designer.
The system works by cooling the oil within a compressor using refrigerant. Basically the system will start up, oil will heat up and temperature will be controlled to a SP of 66 DegC. It is controlled via a valve which releases refrigerant into the system to cool the oil and try and regulate the temperature to 66 DegC.
PGain = 1.02
IGain = 7.74
DGain = 0
Attached is a screenshot of the PV, CV and SV.
PV is orange.
CV is blue.
SV is brown.
Any help with tuning would be greatly appreciated.
Regards,
Scott
