The decentralized robust control problem of a class of uncertain interconnected large-scale discrete time-delay systems
which satisfy the matching conditions is considered.By constructing Lyapunov functions
linear matrix inequality(LMI) is employed.A few sufficient conditions for such large-scale systems are derived.A convex optimization of LMI constraints is formulated to design a decentralized state feedback control with smaller gain parameters
which enables the closed-loop system to be asympt...
