This book is very mixed. It does some things well and some things very badly. What it does well is give a lot of real-world examples and great explanations of the theory/concepts and definitions. What it does horribly however is actually teach you how to do the problems. The approach the authors took to writing this would be much better for a masters level control systems class where you presumably already know the basics and are more interested in designing systems than you are trying to figure out how to actually work through the problems by hand. The only solutions it gives are for the multiple choice problems (which are mostly testing whether you know the concepts). There are no solutions for the problems you actually have to work out. The examples in the text itself are basic to intermediate, but provide little to no help for how to get through the harder exercises. They also have mistakes and the examples sometimes omit very critical steps in showing the solutions to the examples. And it does not just steps like taking a derivative or doing integration, which by the time you get to the point in an undergrad degree when you are taking control systems you will use MATLAB, Wolfram, or your calculator to do anyway, but actually omitting steps in setting the problems up.
Like most of the other reviewers, I think it is way too dense to be of much help in an introductory undergraduate class. The authors seemed more concerned about showing how much they know about control systems than they do actually teaching students how to do the work. If they took about half of the explanatory material out and put in more useful examples then it would be a much better book. Given that this thing is the size of an old-school phone book, it should be much more helpful than it is. If you have a good teacher you can get around some of this book's limitations. If not you will probably need to look on YouTube or do some Google searching to figure out how to do problems.
I debated between giving this two or three stars. Honestly, I see it as a 2.5 overall. If you are in an undergrad class just learning the material it is definitely closer to two stars. Once you actually understand the topic though, and are not as concerned with how to do the problems by hand, then I could see this book being more useful.
