Flight Stability and Automatic Control

Rating:
Summary: A lot of info on aircraft control in a small textbook.
Review: I found this textbook to include a large amount of concisely presented material on all aspects of aircraft stability and control and feedback control system design. It covers everything from the atmosphere, to development of forces and moments and equations of motion, to estimation of stability derivatives, analysis of dynamics and modes of motion, and handy reduced degrees of freedom. It also includes many examples of designing autopilots and stability augmentation systems. I really liked the examples which included both classical and state variable methods. Each chapter also has several interesting example problems. I would recommend this text for anyone in the field of aircraft or missile flight controls. The only dissappointing aspect of the text is what I consider an excessive number of typographical errors. I would caution anyone not to use the equations or formulas without first checking the derivation. The derivations are clear and concise enough that the reader should be able to find these errors.

Summary: An excellent introductory book. Highly readable.
Review: The best aspect of this book is the simplicity in the exposition of ideas and concepts while giving more than enough information for an introductory book. Fully worked out examples are frequent throughout the chapters and helps even further in getting good grasp of new materials. If the reader has taken introductory courses in Vibration and/or Feedback Control, the book should be an easy read. The book is roughly divided into two parts: The flight dynamics part and control part. In the flight dynamics part, the explanation smoothly leads the reader from equation of motion to the concept of stability derivatives and how they relate to dynamic stability. The derivatives are very well explained and then summarized in tables for a quick reference. In the control part, the author starts from the classic linear feed back control and proceeds to the modern state space method and introduces optimal control design using linear quadratic regulator. The control part is an amazing time saver. I have never seen a more efficient introduction to optimal control as applied to aircraft dynamics. If the reader wants a full fledged treatment of optimal control of aircraft, the materials presented here are far from enough, but as an introductory book, this is an excellent exposition that lets the reader get to pace quickly and have straight forward perspective on the subject. Although there were some blatant typos, it is an excellent work and I highly recommend the book.

Summary: Good Fundamentals Book by a Talented Writer
Review: This is an excellent book for the modern fundamentals of aircraft control design. Most subjects are clearly treated with just the right amount of illustrations and examples. The author makes good effort of explaining procedures without resorting to function calls from some software package. The last of the book devotes relatively little space to modern control theory. I would hope this talented writer would create something more advanced in the future that would expand on his treatment of the state observer and the use of the cost function.
