Control theory is tough area as a well. Have a feel for negative feedback is critical to build on. Feedback in simple transistor circuits is a good starting point. Mechanical examples like a toilet float work too.
Check out this link on PID's available today. Note more different "knobs" you can change. That can get you in big trouble too.
I'm far from an expert on that, I know just enough to be dangerous.
