Abstract :
A decentralized adaptive control system, in which the local feedback gains are tuned by the σ-modified adaptive law so as to achieve small output errors with small feedback gains, is proposed. Stability analysis and fault tolerance analysis are performed, and it is shown that if the stability of one of the stable subsystems breaks down and if the control input becomes zero, the local feedback gains of other subsystems are tuned automatically so as to keep the stability of the overall system. The interconnection may involve distributed systems such as a time delay system
