OVERLAPPING DECENTRALIZED CONTROL LOGIC FOR DEDS
离散事件系统结构化状态反馈控制逻辑

A new analysis and synthesis method for discrete event dynamic systems (DED) based onautomaton models is proposed in this paper.The overlapping decedtralized control scheme forDED is given,which arises from practial requirements.First,the concept of overlappingdecomposability for systems is proposed,and then the local controllers for each subsystem ob-tained from decomposition are designed,and the decentralized controllaw for the whole DEDis given.It is proved that the optimality of system synthesis is not lost in adopting such decen-tralized control strategy.These results can be applied to manufacturing systems to give theirreal-time control law.
