Lennart Ljung’s System Identification: Theory for the User is a complete, coherent description of the theory, methodology, and practice of System Identification. This completely revised Second Edition introduces subspace methods, methods that utilize frequency domain data, and general non-linear black box methods, including neural networks and neuro-fuzzy modeling.
Ljung combines careful mathematics, a practical understanding of real-world applications, and extensive exercises. He introduces both black-box and tailor-made models of linear as well as non-linear systems, and he describes principles, properties, and algorithms for a variety of identification techniques:.
Ljung also presents detailed coverage of the key issues that can make or break system identification projects, such as defining objectives, designing experiments, controlling the bias distribution of transfer-function estimates, and carefully validating the resulting models. The first edition of System Identification has been the field’s most widely cited reference for over a decade. This new edition identificagion be the new text of choice for anyone concerned with system identification theory and practice.

I was specifically looking for analysis of subspace methods applied to state space frequency data.
The book let me down. This book is very poor for practitioners in the field. My intent is to implement some algorithms for use on real world problems but this is not the book to do it. I’m used to math heavy texts, but the notation used in this book seemed inconsistent and harder to follow than necessary. While reading I found myself needing to “translate” the math to less clunky forms.
I don’t know if my issues are due to this book in particular or just different notation conventions used across fields, but I’d warn physicists that you may have the same experience as me.
System Identification: Theory for the User – Lennart Ljung – Google Books
Theory for the User, Ljung. Yes, the book is “heavy” in mathematical proofs and the notation will keep you focused. However, you do not need the proofs to apply the material. I applied very successfully the recursive methods, which I studied in the first edition of isentification book, in my early System Identification Control projects.
No, not by any means. It took some very careful studying and very careful programming of the recursive least square algorithms. Then, with the advent of lnnart Matlab System Identification Toolbox, the topic of system identification using Ljung’s 2nd edition of “System Identification: Yes, you will need to have a relative good understanding of Stochastic Processes. However, since the topic of system ID is graduate material, I would anticipate that most readers will have studied stochastic processes as part of their undergrad studies.
It was this workshop, this Toolbox and this text, that took systems ID from my “basement” levels to the very applied levels. Even though I am now retired, I still spend most my days trying to keep up with the advances in Control Systems.
I gave my old copy of this book to an ex-colleague. Now I miss the book; so I just ordered another copy. Might be useful for a mathemtician.
Let me be the first idnetification slam this book as having little practical use. The author uses a very unconventional, inconsistent notation that renders this book virtually unreadable.
The “theory” part in the title is dead on, but what about the “for the user” part? What user is this referring to, an ivory tower professor? Most of the problems at the end of each chapter begin with “prove”, which in my opinion makes this a math identificatjon and not an engineering text. A practical example never surfaces in the text. I would discourage anyone from purchasing this text as their sole source of system identification techniques.
The text is essentially a symbol soup for the user to unravel. Proofs of mathematical concepts are overly brief and rarely given any meaningful context. Moreover, there are little to no practical examples to help guid your understanding. Even with a strong systems background, this book is rarely helpful. One person found this helpful.
The book provides the information to put system ID theory into practice. As mentioned in other reviews, it is very useful if you use the Matlab System Lennarh toolbox. It has provided a basis for a number of commercially available system identification software packages. It is not an “easy read. This book is in all sense the angular stone for anyone who desire to start in a serious manner to develop skills in the System Lhung subject.
This book has all the options, the “theory for the user” are the “kitchen recipies” proper of the topic, this is the techniques that you can idenification without understand the background, and in the other hand it has all the neccesary theoretical support sgstem develop a clear and complete serious idea of the subject, in which case the posibility of gain a much more profound comprehension of the System Identification field is at hand in identificztion text of the book.
This is a very identificqtion speciallity book. The notation can be confusing at first, but it should not be a decisive point for someone who is ready to learn the System Identification subject, in other words, if you have the necessary prerrequisites for study this topic and you must have it if you has reached this far the notation wont be a major problem.
Excellent binding, a high quality product in all aspects. Sorry for mi English.
