A modelling approach of robustness control for regulation systems with Temporal and non Temporal Constraints through Petri Nets

Abstract

Petri nets provide a graphical and mathematical framework for modeling Discrete Events Systems (DES). An ICPN model provides a conceptually modeling framework to represent the system with non temporal constraints. It represents an extension of P-temporal Petri Nets. In this paper we propose an approach to model the regulation quality systems. The proposed approach is based on hybrid Petri Nets which combines Interval Constrained Petri Nets (ICPN) and P-temporal Petri Nets. These tools allow us to evaluate the quality variations and to manage the flow type disturbance. An example analysis illustrates our approach.
