Optimal predictive control of water transport systems: Arrêt-Darré/Arros case study [PDF]

, 2009
This paper proposes the use of predictive optimal control as a suitable methodology to manage efficiently transport water networks. The predictive optimal controller is implemented using MPC control techniques.
