Conduite réactive des systèmes dynamiques étendus à retards variables. Cas des réseaux hydrographiques

Abstract : Supervision and control of extended dynamic systems characterized by non-linearities and important transfer delays is studied in this memory. These systems convey flows at long distances to satisfy human activity uses. The economic importance given to transported flows imposes an adapted resource management. For hydrographic networks, management methods lead to the disturbance rejection without enabling its valorization. We propose a reactive control strategy permitting the control accommodation by switching the setpoints depending on the diagnosed states of the resource, and by taking into account management constraints depending on the costs. The resource state diagnosis implemented in hybrid automaton formalism, is carried out from signal characterization techniques. Steps and algorithmic tools of multimodeling, of which the principal interest is to determine the model number and their operating range, are introduced aiming at simulating free surface hydraulic systems. From these results, a tuning technique of the reactive control strategy was proposed. Finally, the strategy performances are evaluated by simulation software which accurately calculates the system dynamics. The reactive control strategy effectiveness was shown for the resources valorization of hydrographic networks.
