International audienceAn application of modular supervisory control theory to an experimental automated manufacturing system is presented. The proposed application approach is based on three main steps: (i) the modeling of the plant basic control and behavioral specifications in the form of automata; (ii) the automatic synthesis of modular non-conflicting supervisors using a computer tool; and (iii) the implementation of the designed supervisory control. This approach guarantees that the manufacturing system closed loop behaviors do not contradict the considered specifications and are non-blocking. It also guarantees that the supervised behaviors are maximally permissive within the behavioral specifications
