Fault tolerance of autonomous decentralized adaptive control systems

Modem control theory based on the feedback of all states does not give a design method which tolerates some failure of sensors or actuators. Decentralized control, which stabilizes the interconnected subsystems by means of local feedback control, is considered to have more fault tolerance than centralized control systems do. This paper introduces a mathematical model of a decentralized adaptive control and analyzes the fault tolerance of the decentralized adaptive control system, in which an intelligence is distributed as local adaptive controllers.
