First Sentence:
Examples of feedback are found in many disciplines such as engineering, biological sciences, business, and economy.


Fills the gap between introductory feedback control books and more advanced robust control books

Supplies example problems that can be worked by hand, or with MATLAB or a similar software

Presents classical and modern control, taking uncertainty explicitly into account

Covers the basics of robust control and incorporates new techniques for time delay systems

There are many feedback control books out there, but none of them capture the essence of robust control as well as Introduction to Feedback Control Theory. Written by Hitay Özbay, one of the top researchers in robust control in the world, this book fills the gap between introductory feedback control texts and advanced robust control texts.

Introduction to Feedback Control Theory covers basic concepts such as dynamical systems modeling, performance objectives, the Routh-Hurwitz test, root locus, Nyquist criterion, and lead-lag controllers. It introduces more advanced topics including Kharitanov's stability test, basic loopshaping, stability robustness, sensitivity minimization, time delay systems, H-infinity control, and parameterization of all stabilizing controllers for single input single output stable plants. This range of topics gives students insight into the key issues involved in designing a controller.

Occupying and important place in the field of control theory, Introduction to Feedback Control Theory covers the basics of robust control and incorporates new techniques for time delay systems, as well as classical and modern control. Students can use this as a text for building a foundation of knowledge and as a reference for advanced information and up-to-date techniques

Reviews:

The manner this book is written is not very professional. It neither explains why the formulas shown are correct, what each formula means, and how to use them in control implementation. This book may be useful only for those who studied this subject with other books and only need a formula sheet. Another problem of this book is typos. The author is recommended to have more teaching experiences and learn how to explain the subject. The publisher is recommended to inspect typos before the next edition will be in print.


The best recommendation to the writers of textbooks is "Step into reader's shoes." Writer is an expert of the subject. He knows the subject very well. Readers are not. Readers need enough guide to follow what is written in the book. This book often jumps into a conclusion without enough intermediate steps. Equations come out of blue. I was perplexed by that the writing is sparse and crude. Thus I stopped reading this book and returned.
