Modeling and control of a high-speed discrete event system

In recent years fuzzy sets theory has been widely used in the control of many complex industrial continuous processes. However, there are few researchers (to the authors´ knowledge) that try to use this theory in the domain of discrete event systems (DESs). In this paper, a fuzzy controller for a high-speed discrete event system has been developed. This controller consists of a set of local fuzzy controllers which can be linked to a supervisor. Each local fuzzy controller it used to control a specific component of the line. These components are generally multi-input single-output processes, In order to validate the controller´s instructions, a unified formalism based on hybrid Petri nets is used to simulate the system and the interactions existing between the system and the controller
