Approximation of Large-Scale Dynamical Systems (Advances in Design and Control, Series Number 6) Reprint Edition

Dr. Athanasios C. Antoulas is one of the world's leading authorities on model order reduction. In this book he clearly differentiated Singular Value Decomposition (SVD) methods and Krylov subspace projection methods and their explanation in part III and IV is excellent. The fist two chapter of introduction and preliminaries give you sufficient background to understand Part III and IV. The book does require some familiarity with numerical linear algebra and may be difficult for a new comer in the area to follow, however the way it is written it can be used both by engineers and scientist. A must-have book for any one working on model order reduction or dealing with large scale dynamical system. By reading this book I clearly understood the concept of reachability and observability and how it is applied to better understand a dynamical system. Overall a book with excellent source of knowledge, both as text and reference book. My recommendation definitely 5 stars.
