Abstract
A control method and apparatus incorporate a network model simulating hydraulic phenomena within a water distribution network whereby the pressures and flow rates within the water distribution network are controlled by an optimizing unit for inputting the current total demand as a model input and computing manipulated variables or control amounts for optimizing the pressures and flow rates in accordance with a network algorithm and a correction computing unit for computing the necessary control amount correction values for correcting the deviations from the estimated pressures and flow rates in accordance with a sensitivity matrix indicating the effects of variations in the control amounts on the pressures and flow rates.
