AN ON LINE COURSE FOR SUPERVISORY CONTROL TEACHING

摘要

Discrete event systems (DES) describe the behavior of a plant as it evolves over time in accordance with the abrupt and asynchronous occurrence of events. Such systems are encountered in a variety of fields, for example sensor or actuator faults diagnosis, robotics, computers, communication networks and traffic. The control objectives of the supervisory control of DES are to prevent a set of forbidden states from being reach, to preserve the reachability of some non forbidden states, while at the same time enabling a maximal set of achievable state sequences. The aim of this paper is to introduce several approaches for the supervisors synthesis, a Matlab tool SUPCON and an on line multimedia Petri nets and DES course.
