Distributed Cooperative Regulation for Networked Re-Entrant Manufacturing Systems

Dear Editor, This letter focuses on the distributed cooperative regulation problem for a class of networked re-entrant manufacturing systems (RMSs). The networked system is structured with a three-tier architecture: the production line, the manufacturing layer and the workshop layer. The dynamics of re-entrant production lines are governed by hyperbolic partial differential equations (PDEs) based on the law of mass conservation. Distributed cooperative controllers are designed for the leaderless synchronization of the networked system. Numerical simulations validate the effectiveness of the proposed control scheme.
