Terry Davis, author of TempleOS, demonstrates his SimStructure physics simulator and builds a PID controller using math from Numerical Recipes in C. The description notes PID controllers are used in everything from rockets to espresso machines.

Why Hacker News points people here: HN links it with timestamps as an early, hands-on demo of control theory and as a curiosity from Davis's work.

“He starts talking about PID controllers at around 3:40.”HN comment, 2022

“Terry Davis was doing this 15+ years ago”

Early demonstration of balancing simulation using calculus and control patterns.

Not sure why this has to be AI specific.. Terry Davis was doing this 15+ years ago: this video Seems to be more of an issue of knowing calculus and control system patterns.

Heh, I haven't seen or read NR but added it to my wishlist after watching Terry Davis mention it [at 8:15] this video Seemed to work well enough for him.
