Making use of the analytical network model of this installation and using presented below, the so-called Virtual Distortion Method (VDM), the control of water supply can be performed. Minimization of supply pressure in inlets to the network, subject to inequality constraints imposed on outlet pressure (in chosen nodes) is discussed. Taking advantage of pre-computed influence vectors, the real-time control strategy can be realised with small computational effort and therefore, can be managed with use of hardware-based controllers. Non-linear constitutive relation (water flow vs. pressure head) has been assumed.展开更多
