ウェブ張力制御系の重複分割分散制御設計 Overlapping Decentralized Controller Design for Web Tension Control System
Web tension control system is regarded as a large-scale system composed of a number of subsystems associated with tension control and speed control. Then the control system should preferably have a decentralized information structure. Since the concept of a subsystem comes from the controller design strategy, the system decomposition is not unique. This paper proposes an overlapping decentralized control methodology for a web tension control system. By employing the overlapping decomposition, the interactions among subsystems are purely disturbance in terms of physical variables. In this case, it doesn't require crossover frequency assignment to each subsystem, and all the interactions are to be minimized. H-infinity controller design procedure is adopted for constructing decentralized controllers. The calculated results confirm the significant advantage of our methodology.
