DECENTRALIZED AND COORDINATED CONTROL OF DISCRETE EVENT SYSTEMS DESCRIBED BY CONTROLLED PETRI NETS

In the paper, place-interconnected petri nets are introduced, which are composed of several subnets with some common places. For discrete event systems which can described by place-interconnected petri nets, a decentralized and coordinated control framework is introduced to realize the forbidden state control of them. A aynthesis method of coordinated control is developed for the minimal constrained control of them, it is efficient in computation.
