Abstract
The problem of achieving stability and certain H/sub /spl infin// performance objective for a large-scale system by a decentralized feedback law is considered. It is shown in order to reduce the sensitivity to the interactions, the states of the other subsystems can be considered as external disturbances for each subsystem. An appropriate H/sub /spl infin// controller is designed for each subsystem. Solving H/sub /spl infin// problems for the subsystems, the sensitivity to the interactions is reduced and the performance problem which is formulated as the standard weighted mixed sensitivity H/sub /spl infin// problem, is solved. Sufficient conditions are derived when satisfied to assure the overall stability.
