Decentralized Control of Large-Scale Systems

Large-scale system refers to a system that consists of several interconnected subsystems. In large-scale systems it is often desired to have some form of decentralization in control structure. In fact, for such systems it is not realistic to assume that all output measurements can be transmitted to every local control station. Problems of this kind appear for example in electric power systems, communication networks, large space structures, robotic systems, economic systems and traffic networks, to name only a few. Typical large-scale control systems have several local control stations which observe only local outputs and control only local outputs. All controllers are involved, however, in the control operation of the overall system. Decentralized Control of Large-Scale Systems provides various analysis and design techniques for decentralized control of large-scale systems. A systematic study of multi-input, muti-output systems with a special focus on industrial applications is given.
