Feedback Systems: An Introduction for Scientists and Engineers

This book provides an introduction to the mathematics needed to model, analyze, and design feedback systems. It is an ideal textbook for undergraduate and graduate students, and is indispensable for researchers seeking a self-contained reference on control theory. Unlike most books on the subject, Feedback Systems develops transfer functions through the exponential response of a system, and is accessible across a range of disciplines that utilize feedback in physical, biological, information, and economic systems.

Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. They provide exercises at the end of every chapter, and an accompanying electronic solutions manual is available. Feedback Systems is a complete one-volume resource for students and researchers in mathematics, engineering, and the sciences.

Good for Concepts and Beginners

By LaserBeam - February 17, 2011

I used this book in a course on classical control theory. It's a great book for explaining concepts in control theory. You'll need background in calculus, differential equations, and linear algebra in order to understand it.

The book is great for giving you an understanding of control theory. Whoever said that there are errors in the book is correct, and you will notice errors if you choose to work out the steps that the author chooses to skip. The author has created a list of Errata to go through at [...]

Not a very helpful textbook

By Andrew - December 26, 2012

Needed this for a class. Ended up not using it too much, and when we did use it the book it often contradicted what was taught in class and was certainly not used in the same order. Other controls & systems textbooks I have read are much more concise and less abstract than this one.

Useless for learning

By mbandpch - November 25, 2008

I came into my control theory course, for which this book was a required course text, excited to learn about a very interesting and useful topic. Instead, this book came close to making me hate the subject.

Frankly, I have had more than enough of this atrocity. The book is riddled with a ridiculous number of typos and errors that range from amusingly glaring proofreading lapses at least several times per chapter, like "A block diagram of a basic feedback loop is shown in Figure 11.1. LDH](6 Jan 08) Reworded the third and fourth sentences. OK?" to extremely frustrating serious errors in formulas. I actually doubt that the book even got proofread by anyone at all. I do not believe I would be exaggerating by saying that there are several hundreds of errors in these 400 pages, giving it the honor of being the most error-riddled science text that I have ever read throughout high school and college. In addition, equations with mysterious origins, surrounded by explaining text... read more
