Parameter estimation for timed and continuous Petri nets: Application to the identification and monitoring of hybrid systems
Résumé
Petri net models are useful tools for the modelling of discrete event systems and hybrid systems. This paper is about the parameters estimation for two classes of timed PN: T-timed Petri nets and continuous Petri nets with variable speeds. The parameters to be estimated are either incidence, either temporal parameters. Data based and model based methods are proposed. In each case, on line and off line implementations are detailed. As a consequence, identification and monitoring applications for hybrid systems are described
