Differential Pressure Control - an overview ...

Philip Thomas, in Simulation of Industrial Processes for Control Engineers, 1999. 23.5.8 The change in differential pressure with speed, dΔp/dN. The response is assumed instantaneous because of the very fast establishment of liquid flow. It is a total derivative from the perspective of the differential pressure control loop, where the liquid control valve position is assumed constant.
