Autonomous distributed adaptive control system

Decentralized control system is considered to be superior to centralized one from the viewpoint of fault tolerance, on-line maintenance, or on-line expansion. In this talk, we introduce a fault tolerant decentralized adaptive control and discuss the principles of autonomous distributed systems. The objective of the proposing decentralized adaptive control system is to maintain the overall system's stability in the face of a local compensator's failure. Because the failure may be modelled as a change of interconnections, the proposing decentralized adaptive control system is based on the high gain adaptive controller which can reduce the sensitivity from the interconnections to the output of each local subsystem. We are interested in the self similarity of decentralized systems, as the principle of the fault tolerance in decentralized systems. The property to maintain the stability in the face of a failure can be explained by the property that a certain kind of the structure of the system is not changed by the failure. We will explain the fault tolerance of the proposing system by using this self similarity.
