This comprehensive treatment of the analysis and design of continuous-time control systems provides a gradual development of control theory—and shows how to solve all computational problems with MATLAB. It avoids highly mathematical arguments, and features an abundance of examples and worked problems throughout the book. Chapter topics include the Laplace transform; mathematical modeling of mechanical systems, electrical systems, fluid systems, and thermal systems; transient and steady-state-response analyses, root-locus analysis and control systems design by the root-locus method; frequency-response analysis and control systems design by the frequency-response; two-degrees-of-freedom control; state space analysis of control systems and design of control systems in state space. For control systems engineers.

Engineer? Buy this book!

Customer Rating:

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

Customer Rating:

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

Customer Rating:

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

Customer Rating:

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.

Great book!	Customer Rating:
This book helped me a lot while I was studing Control Theory at college. It has very clear examples and it is well written.
