Real-time Adjustment of Pressure to Demand in Water Distribution Systems: Parameter-less P-controller Algorithm

Remote real-time control is currently the most advanced form of pressure management. Here the parameters describing pressure control valves (or pumps) are changed in real-time in such a way to provide the most optimal pressure in the water distribution system (mostly at the consumer location), as demand and reservoir levels change. An existing parameter-less P-controller based on the flow in a pressure control valve being known is argued to be easy to implement, and is used to develop an efficient controller to adjust the pressure. Its performance compared to an analogous existing parameter-dependent controller is discussed.
