Reddit mentions of Control Systems Engineering

Shigley is good for machine design. As far as electronic controls and automation goes I'm not sure, but you would probably want to start out with some books on mechatronics and possibly mechanical control systems. Like this maybe.

Through the knowledge based in the books: Communication Systems - Carlson and Control Systems Engineering
... I have found that one can find within a specified accuracy and equivalent system. One method I know of is to expand the mathematical series into a form known as a Taylor series truncated to a polynomial to the order of your choosing, which yields sufficiently accurate approximation. The Laplace transform is applied to the Taylor polynomial. The Inverse Laplace transform is then applied to the transformed Taylor polynomial. This results in beautifully factored results; often useful for stability analysis such as the Rooth-horwitz or graphically plotting the Poles and Zeros.

If your math-foo is strong, perhaps the following link will better describe the process of sensitivity analysis after such transformations of been applied Christiansen

The power of this occurs because the final form after an inverse transform is repetitious, and referenced through a table one piece at a time; resulting in a visually appealing equivalent equation.

Sorry about the quality of the links, Its quite hard to find relevant internet available sources on topics which have pre-requisits of Matrix Algebra and Differential Equations. If these topics interest you, consider applying to a Engineering University, cause entire Junior/Senior level lesson plans are devoted to teaching how to take measurement data and converting them into a form of which we may analyze them. We prefer the factored form, for it has some of the easiest to compute analysis. Most of the links I provided already assume that one knows how to convert into the factored form, or more specifically forms which come out of the inverse Laplace transform.

Control Systems Design: An Introduction To State-Space Methods

Control Handbook, 2nd Ed

Those are some that I have. The Nise book is excellent, the Dorf book is as well, it was my primary text for Controls I & II, supplemented by the Kuo book. The latter has more on digital controls. All of those three focus primarily on classical control theory and methods, but the Nise book goes into more depth on modern methods. I got the state-space methods book because it's more focused. The Control Handbook is a beastly collection, but it's very broad, hence not possessed of much depth. It's more of a reference than a text.

If you want to dive deeply into PID control, look no further than Akstrom and Hagglund's works on the subject, it doesn't get much better.
