Abstract

In this paper, two main results for uncertain large-scale systems with time-varying delays are derived. The first result is the presentation of a sufficient condition to test the robust stability for large-scale time-delay systems with unstructured time-varying uncertainties. By checking some Hamiltonian matrices and solving some algebraic Riccati equations, new bounds on the unstructured uncertainties are estimated so that systems remain stable. The second result is the successful design of decentralized dynamic compensators, which use only those local output variables, to the stabilization problem of large-scale time-delay systems. No constraint of matched condition is imposed on the interconnection pattern. Numerical examples are given to illustrate the presented results.
