Abstract
Based on the concept of place invariants of Petri Nets, supervisors for discrete-event systems can be synthesized so as to have a set of operation constraints respected by the controlled system. The implementation of this technique in a manufacturing cell is presented, with detailed description of modeling, supervisor design and programming, in STL language, of the PLC which controls the cell. Important issues such as: supervisor permissiveness, comparative analysis with techniques based on automata, as well as the systematization of the procedure for application to other systems are also discussed.
