Many years after leaving college, I've started playing with closed loop control systems for small toys. (Think: science projects for kids!)

This book was an excellent re-introduction to Bode plots, transfer functions, control loops and compensation. There was a wealth of practical information on modelling control loops containing various degrees of complexity. The sections on second-order loops and output stiffness were particularly useful for my purposes. Your mileage may vary depending on your application, but the book includes a good range of examples, and has something to offer any engineer doing practical circuit design.

I took control theory in college and found it hard to grasp. The mathematics involved in analyzing control loops with higher order systems became daunting and difficult to postulate. Several years out of school, I ordered this book to help refresh myself in the principles of control loop design. Although the information presented is practically valid, the information is hard to decipher. The author's writing style is difficult to follow sometimes. I almost think the book was written quickly due to partially completed thoughts in sentences, awkward sentence structure, and run-on sentences. The chapters seem to be out of order and I found myself jumping forward and backward trying to tie the author's concepts together. I think that if one had never taken a control theory class and read this book, they would struggle with the topic due to the amount of "de-cyphering" required to comprehend the text. I believe the author does know what he is writing about but has trouble communicating his ideas in written text. If the author intends to write again, I would suggest a third party somewhat proficient in the subject manner check the grammar of the text.

This book is very simple and preliminary. I had bought this book with the intention of getting deep insight into feedback compensation networks that go in day to day power supply circuits. Unfortunately, I was disappointed. Even some general books like Switching power supply and Power supply cookbook have good amount of detail on compensation circuit. If you are a beginner, then this is probably the book for you.
