Abstract

See full text

The disclosure describes a method for operating a flow-control valve that includes comparing a desired flow with an actual flow through the valve and re-calibrating a valve iso-curve at periodic intervals when the actual flow falls outside of a predetermined threshold relative to the desired flow. When operating in a nested control loop based on a control parameter, a flow setpoint is selected based on the control parameter and maintained independently of pressure across the flow-control valve.
