The robustness of pole assignment in a specified region for perturbed large-scale systems is investigated using the Lyapunov approach. Two theorems are proposed to guarantee that all the eigenvalues of the overall perturbed large-scale system are located in a specified region. The decentralized controllers from local state feedback are designed to satisfy the requirement of robust pole assignment. An example is given to illustrate the proposed method.
