IDENTIFICATION OF DISCRETE EVENT SYSTEMS USING ORDINARY PETRI NETS

Abstract: This paper presents an identification method of partially observable Discrete Event Systems (DES) using ordinary Petri Nets. The proposed method is absolute, sequential and multiple. It consists in building the compartmental model, computed off-line, for a DES in a Petri Net (PN) form. The developed method is based on the use of the input/output sequences constructed during the system evolution. The proposed algorithm is illustrated by the help of a simulation example
