The problem of robust bounded-input bounded-output stabilization for a linear large-scale system made of several subsystems with nonlinear and statedelay perturbations is considered. Applying a stabilizing local state feedback to each subsystem, sufficient conditions for the robust bounded-input bounded-output stabilization of the system are presented by proposing a new Lyapunov-type theorem and combining with the matrix Riccati equation. The conditions obtained are given by means of positive definite matrices or a set of scalar inequalities. An example is given to demonstrate the validity of the obtained results.
