Synthèse de Lois de commande pour la configuration et la reconfiguration des systèmes industriels complexes

Abstract : The presented work deals with the synthesis of control laws in uncertain context of
the automated production systems. The uncertain one is characterized here on the one hand by the
unpredicted variations of customer requests, but also by the failures of resources. The approach,
localised into level 1 of the CIM, and in particular within the coordination modules of the functional
chains, is integrated in a system of Supervision, Monitoring and Control. The approach considers
globality from the process which leads to the reconguration of the control laws. Indeed, it proposes
not only one method of modelling of an operative part using a formalism adapted to process complexity
but also a technique of control law synthesis based on the research of paths in a graph. The suggested
modelling, near that used in the automatic planning eld, is based on a set of operations which describe
the dynamics of functional chains and theirs eects on product ow while taking into account the
security and environmental constraints. The originality of the synthesis algorithm is the compromise
between the complexity of the used graph and the solution performances.
An application example based on a real manufacturing process, the platform SAPHIR of the
Laboratoire d'Automatique de Grenoble, and on the software workshop developed on the basis of
proposed synthesis algorithm illustrates the contributions of our approach.
