I am just completing a course in discrete time systems, with this book as the textbook. Besides mediocre instructure from the professors, this course's main detraction is this book. There are very few derivations or explanations for many of the formulas, which tend to help me stay interested in the material. Phillips and Nagle have done a terrible job and I feel that I will have to relearn the material when I get to grad school. This book is written from the standpoint that the reader is an experienced engineer who has been working for years; it attempts to make extensions from the analog world to the digital world, and does so very badly. Why my professors chose this book, I will never know. There are very few examples within the chapters, and no answers for any of the problems. As a final note, the book is full of typos and errors. Whatever you do, don't buy this book!

Yup, a brief glimps at this book will tell you it won't be a smooth ride like Franklin's 'Digital Control of Dynamic systems'. I have the old edition of franklin's book and it's almost half the size of this book.

Well let's not judge the book by its cover.

It's a lot more comprehensive then Franklin's, and is composed of 15 chapters which include (in addition to Franklin's standard topics) :

*An entire chapter on Stability Analysis Techniques

*An entire chapter on Pole-Assignment Design and State Estimation

*And most importantly: the book can also be used as a text (or reference text, at least) on Digital Filters (As the author mentions in the preface), Three chapters are completely devoted to Digital filters:

Ch11: Sampled Data Transformation of Analog Filters

Ch12: Digital filter Structures

Ch13: Microcomputer Implementation of Digital Filters

I've taken this book in a senior level course on digital control systems, and most of the students in class were convinced that the book was too advanced for an undergraduate course, and I could't agree better. I think an exposition to the concepts of difference equations, sampling ,and the z-transform is to be done at an earlier stage (like in a course on Continuous and Discrete Signals and Systems) and not to be first introduced in this book, which seems to assume mathematical fluency and maturity of the reader which is beyond most senior level students.

Advanced book. Graduates yes, Undergrads no. That sums up my opinion.

Do not expect to learn anything from this book. The examples have holes. It will have you flipping between 6 different places in the book when it references other pages. The instruction assumes too much prior experience. It's the most frustrating book I've ever owned to supplement the dryest class I've ever taken.

Less or simple examples, and focus more on control maths than practical applications. It lacks details, and strong examples. Many students had problem follwing this book. You definetly need addition book as a refrence.

I used this and a few other books for supplementary study when I took a graduate level course in digital controls. In terms of intelligibility, this book was more helpful than any other, and was substantially superior to the class text.

As a Graduate student. I think this book is very hard to understand. I took long hours to understand some of the topics especially the space state representations.
You should know very well your fundamentals of control system and I recommend to take the Linear System SPace Systems before of this class.
If you understand chapter 2 completely... you will not have problem with the rest of the book.
