By the way, its true name is "negative feedback control".
No. That's like saying a car's true name is muffler.
Bode along with Harold Black, Harry Nyquist, all contributed parts to control theory while at Bell.
Boyd incorporated their work to formulate OODA, which is a distinct thing and very much his invention.
The really important thing about "feedback control" as developed by Black, Nyquist, et al. wasn't that they realized it's a good idea to check to see whether your plan is actually achieving its goal, and correct if it's not. That's just common sense, after all (although the usual disclaimer about common sense being uncommon applies).
The real technical contribution of "feedback control" is that true feedback, in the sense of a dynamic system, can control a system without having to build a model of it. I.e. if your control system is fast enough relative to the system it's controlling, it doesn't have to _predict_ anything, it can just _react_.
Which, if you think about it, is really the _opposite_ of what people usually mean when they say your manager gives you feedback in your performance review, customers give you feedback on your product, etc. When you get that kind of feedback, you still have to figure out what it means in order to do anything with it.
