Robust Stabilization of Large-Scale Discrete-Time Systems with Time-Delays

시간지연을 갖는 이산시간 대규모 시스템의 강인 안정화

This paper describes the synthesis of robust decentralized controllers for uncertain large-scale discrete-time systems with time-delays in subsystem interconnections. Based on the Lyapunov method, a sufficient condition for robust stability, is derived in terms of a linear matrix inequality(LMI). The solutions of the LMI can be easily obtained using various efficient convex optimization techniques. A numerical example is given to illustrate the proposed method.
