Discrete decentralized observation of large-scale interconnected systems

A new approach for the design of discrete decentralized observation schemes for large-scale interconnected systems is considered. The design is based on stability result that employs the notion of block diagonal dominance in matrices and the reasonable bound estimates for the discrete Lyapunov matrix equation. The major contribution of this chapter is the demonstration of how the observer's gains can be tailored systematically to the existing interconnection pattern within the overall system. Although the present results are developed in the context of decentralization observation, they can be extended to the design of decentralized stabilization and to the design of decentralized model reference adaptive identification schemes. Simulation results on a numerical example are given to verify the proposed design. © 2009 Springer Science+Business Media LLC.
