Eigenvalue assignment for dynamically interconnected systems with delayes

Characterization for the class of decentralized feedbacks that is necessary for achieving arbitrary eigenvalues for large-scale dynamically interconnected system containing delay, is given. By expanding the system´s state space, the delay disappears. Feedback gains are designed in the extended state space but implemented in the original state space. Local autonomy of subsystems-interconnections is emphasized in the proposed assignment procedure by coordinating local solutions.
