Not sure why this has to be AI specific.. Terry Davis was doing this 15+ years ago: [VIDEO] Seems to be more of an issue of knowing calculus and control system patterns.
Read original comment ↗Heh, I haven't seen or read NR but added it to my wishlist after watching Terry Davis mention it [at 8:15] [VIDEO] Seemed to work well enough for him.
Read original comment ↗I assume it's this video ("Terry Davis Demos SimStructure (2016-08-25)"): [VIDEO] He starts talking about PID controllers at around 3:40.
