On the complementarity of different types of modelings from 'computer science and communication networks' to 'automatic control'

摘要

The global study of a closed loop control system based on a real-time distributed system is presented. The distributed system Quality of Service (QoS) is first evaluated using Stochastic Timed Petri Net and then integrated into the closed loop control system model (transfer fimction), used to display the impact of distributed system characteristics (delays, losses, message transfer protocols, messages scheduling via the transmission resource) on the stability of closed loop control system. This work aims at emphasizing the advantage of modeling the two domains.
