Feedback Control of Large Scale Systems

This book presents the basic methods of feedback control in large-scale systems, showing how multivariable feedback theory has to be extended to solve analysis and design tasks for interconnected systems. Emphasis is laid on the derivation of methods which have a decentralized information structure, that is to say those which involve several weakly coupled decision units for analyzing the given system or designing the controller. The techniques that are presented are intended as a basis for exploring more specific and sophisticated methods that are of recent derivation. The theoretic background of the subject is presented together with an analysis of the engineering methods and results, which assess the relevance of methodologies to a variety of problems and differently constructed systems. The book is aimed at both students and practising engineers.
