Fuzzified Petri-Nets and Their Application to Organising Supervisory Controller

摘要

A model and the decision reaoning processes of a two-layer organising supervisry controller for complex systems have been developed. it is based on fuzzy Petri-net algorithms and fuzzy rule production system for decision and command control. This model follows the fundamental idea of the original intelligent controller of G.N. Saridis, but adds on a new generic property. This fuzzy-Petri-net organising controller employs the advantages of both the qualitative modelling potential of L.A.Zadeh's fuzzy logic and of the discreteevent genesis of K.A.Petri's networks. Thus is accomplishes full compatibility of mathematical formalisms of the organising and co-ordinating levels of G.N. Saridis' architecture and greatly reduces the rules needed due to possibility distribution evaluation and petri-net-supported reasoning in comparison with Stellakis-Valavanis fuzzy solution for the organiser.
