Synthèse de lois de surveillance pour les procédés industriels complexes

Abstract : This work deals with the supervision of manufacturing systems. It is mainly directed towards the synthesis of monitoring laws adapted to the industrial requirements. The monitoring law is obtained from a Supervision, Monitoring and Control Reference Model that contains the set of supervision, control and monitoring treatments that can be applied in failure situations for any manufacturing system. The synthesis method proposed is based on a process close to the one used to synthesizing self-compensating devices in the automatic control for continuous systems. This method consists in a successive reffining of the reference model with a progressive integration of a set of four properties. Those properties, security, ecology, quality, and productivity must be evaluated by the user by using a set of grids establishing a relationship between the impact of four failure symptoms with the set of properties to be reached. This evaluation is related to the physical resource. An application example based on a real manufacturing process, the SAPHIR research platform on production systems of the Laboratory of Automatics and Control of Grenoble shows the contribution of this approach. The results show the advantages of this approach characterized by flexibility in the failure treatments proposed, by a systematization of the method proposed and by the respect of the expected properties.
