In a large-scale control system, operation must be continued even in the event of fault occurrence, during maintenance or during expansion. As a result, fault-tolerance, on-line maintenance, and on-line expandability are required. To attain these properties, an autonomous decentralization concept has been proposed. Autonomous controllability has been defined as the property whereby high reliability, on-line maintainability and on-line expandability of the system are assured. In this paper, autonomous controllability is discussed in the case in which each controller has imperfect information about the state of the system. The results are applied to a computer network.
