 "Engineer? Buy this book!" | 2008-07-18 |
| - Reviewed By karlgluck |
As an undergrad Electrical Engineer, I wish I had found this book sooner! In the first few chapters, Ogata concisely (yet thoroughly) explains everything that was taught in two semesters' worth of signal theory and complex linear algebra. The explanations are complete and Ogata doesn't cut corners with the dreaded "it is easily shown that..." cop-out many technical text authors use to drive us undergrads slowly insane.
Furthermore, he goes out of his way to show the relationships between ideas and reinforce properties and behaviors introduced earlier in the book. Whether you're looking for a powerful and fast introduction to control theory with linear systems (the first few chapters) or a desk reference for advanced material (the later chapters), this is the book for you. |

 "Very Poorly Written" | 2007-11-27 |
| - Reviewed By bspratling2 |
| As a student taking a class taught by this text, I can confirm that this book is one of the most poorly written textbooks I have ever used. I suppose I wouldn't feel qualified to comment if I hadn't received the only A in the class on our last midterm. The author does not define his jargon adequately and does not list important vocabulary items in the index; thus the reader cannot find definitions in the text without riffling through every page. The examples are not just plentiful, they're the only thing in there. Except for the ambiguous prefaces on every chapter, there are very few explanations of the motivation for anything, which leaves the students in the class asking "open loop or closed-loop transfer function?" several times in the chapter on frequency response. It's true some pages contain a step-by-step process of what to do, but many times the idioms describing the inputs, the equations or the results analysis simply aren't defined and have to be divined. The combination of, for instance, the Routh Stability Criterion and MatLab code make this book an uncoordinated jumble of modern, computerized, mindless control-design algorithms and imprecise, antiquated, slide-rule level guesswork. Comparing this to, say, Vallado or Otsuka, Ogata holds no candle. Our professor commented that after using this book in school himself, he failed the class, had to re-take it, become the TA for it in grad school before he understood it. Regardless of the quality of the professor, well-written textbooks don't leave people with that experience. If there is a better text, please someone drop a hint; all I know is, this one ain't it. |

 "great book but lacks application problem" | 2007-05-14 |

| Great book but lacks application problems. I am told this book is more for an indepth analysis of topics already learned from other coureses with the addition of Observers,state observer feedback, Intro to the use of Kalman filters, state variable feedback, and optimization. The optimization section could be better but if you have a great teacher its a good reference. I had used this book as an undergrad and told its a reference for grad students. |

A true introductory book on Control Engineering
I love this book. The book is written in a very clear and readable way. All topics explanations are simple to understand. All examples are shown step by step, so you can really understand the ideas and applications associated with each one.
Katsuhiko Ogata's book is unbeatable as an introductory textbook for Control Systems at the undergraduate level. This was my text book in college, so I can recommend it base on my first hand learning experience. |

This text is not just thorough in its covered material. It covers more material than all other undergrad. level control texts I've ever seen. It treats thoroughly both state-space and the transform approaches which makes this text somehow unique. The text opens your eyes to the P,PI,PD and PID controllers in the very beginning which is thrilling for first time control students. As a matter of fact, the text is more focused on mechanical engineers interests than those of the electrical engineers. I consider the concept itself neutral :) which ECS/EE majors might share with ME(s).
As a student you will find the text written in a way that it walks through the concept and practice with you step by step. It teaches you matlab the same way (step by step!). If you are using another text through this course you may use this one as a supplementary text since it covers almost every topic used through the undergraduate level. The multi input multi output system is covered in every control systems text except the fact that none of those I read (more than 5 'big' texts) stated how would you evaluate the values of betas in the B matrix!. Yes, that was no big deal! :) but for me, I always appreciate to see how/where did you get it more than how does the final form look like!
As an undergraduate student I would say, you can either use another text and consult this one just in case! or you can get this one and save the other text's money ! |

This book is very good. I really like the way the formulas are given, with all the variables immediatelly defined. When reading it was amazing. As the questions arose in my mind as to what something meant, the next sentence or two satisfied my curiosity.
While other books tend claim that a piece of information is "beyond the scope of this text" (yet then expect knowledge of the topic), Ogota takes a couple of extra paragraphs to explain the basics of what is needed for better understanding. |

| This is an excellent controls text. All concepts are beautifully explained and developed. The examples in the book are clear and concise and the exercises cover a broad range of control system design applications. One of the greatest perks of this book is the extensive coverage of MATLAB applications to control system design. Not only do you learn how to do it mathematically but you learn how to program and let MATLAB aid you. You get double the learning for the price of one text! |

| First of all, the book is written by an extraordinary authority in the field, one of few such professionals in the world. It covers the whole subject of modern control engineering, so if You know most of it, what is in the book, You know a lot of the subject. There are many clear and precise physical models, block diagrams, MatLab instructions, the results given by a computer, the problems solved or/and explained by the language of mathematics and theory of control. ALL IN ONE. The book is The Art of Modern Control Engineering. However, You have to have at least some physical and mathematical bases to learn and see the beauty and art of it all. |

| I used this book for two semesters. The only downside is that this book is too thick, but the new edition looks better. I found the MATLAB program(s) very useful, in addition to a bunch of solved sample problems at the end of each Chapter. I have been told that the latest edition has information on Signal Flow Graphs (Mason's Rule), which is very critical if you are analysing the topic of Controls from an Electrical Engineer's point of view. |
