Commande robuste des ateliers manufacturiers à contraintes de temps

This paper deals with robust control of manufacturing systems including time constraints and running in a repetitive mode. Controlled P-Time Petri nets provide a control oriented model taking into account all time specificiations. A theoretical approach based upon lemmas is used in order to build locally controllable paths. It is extended further to a more general controllable notion. Finally, a theorem and a lemma provide a sufficient condition for a dynamic robust control which avoids breaking the specifications constraints. As an illustration this new control strategy is applied on a multi-product job-shop without assembling station.
