Hi every body,
I'm working on an anti surge control for the centrifugal compressor and I need to configure an equation on the PLC to control the minimum flow to the inlet of the compressor. I think the PID function that is available on on the PLC DOES NOT REALLY FIT TO THIS operation, because the PID will try to move the anti surge valve to fix the measurement near the setpoint. however the surge control is based to bring the operating point far than the setpoint. please help me to figure out how to configure a mathematical equation with three action P, I, and D to achieve at a good control.
Thanks for your help.
