What is the generic name for the type of engineering that is seen in e.g. segways, that reads a metric, makes small adjustments by calibration, and the whole organism becomes a thing standing up straight. I.e. you don't calculate all factors and then decide the lean, you build a autonomous system with metrics, rules and a success critera?
Cybernetics? Proportional-Integral-Derivative? Feedback control? Control systems?
This is an important piece of the puzzle.
Control systems enginering seems to be the field i'm looking for.
This will be useful later.
