| Abstract: | The delay-dependent decentralized robust stabilization problem for an interconnected singular large-scale system with uncertainties is investigated by using Lyapunov stability theory and the delay-integral matrix inequality method. The purpose is to design a memoryless state feedback decentralized controller such that the whole closed-loop system is robust asymptotically stable. Sufficient conditions for the delay-dependent decentralized robust stabilization are obtained in terms of a set of matrix inequalities. The results depend on the size of the delays and are given in terms of matrix inequalities. A numerical example is provided to illustrate the effectiveness and the availability for the design. |
