Reconfiguration de lois de commande et accommodation active des modes de fonctionnement pour les systèmes plats

TL;DRAbstract

The work presented in this memory concerns the control reconfiguration of dynamical systems with variation of operating modes in order to ensure the desired performances. For the control of dynamic systems, two approaches of accommodation have been proposed. The passive approach presents a controller with fixed parameters that doesn’t ensure the same performance for different operating modes and an active approach in which the controller settings can be updated according to the variation of the detected operating mode. Our work has therefore focused on this second approach based on multi-models system representation. The modelling errors corresponding to the variations of operating conditions are detected in this case by detection and localization algorithm, consequently, a reconfiguration strategy based on flatness-based switching control is proposed. This approach guarantees the control and the tracking of a reference trajectory. In fact, we have synthesised a discrete flatness-based
