Abstract :
This work deals with the robustness of dynamic discrete event systems including time interval constraints. It presents a method to compute the passive robustness by the decomposition of the P-time Petri net model into four sets. A computing algorithm of a lower bound of the maximal time disturbances allowed on a given point is provided. Also, we focus on the active robustness by giving some definitions and lemmas. Finally, we present a theorem containing a local sufficient condition for the active robust control use.
