I know next-to-nothing about this topic, but the following question has
popped into my mind several times.

It seems like folks generally (and perhaps this is totally wrong) design
PID controllers by basically selecting what they think are "good"
constants for the proportional, integral, and derivative terms. That is,
they just sorta play with their systems and tweak the terms until it
seems to work smoothly.

However, how do you know that a particular configuration is stable?
