I would love to hear a BoingBoing commenter who knows a little bit about PID Curves tell us how what is going on here is different. I did enough tinkering with multirotors a few years ago to learn about how PID calculus is embedded in EVERYTHING, from cargo-ship autopilot to home thermostats to car cruise control.
Is what’s going on here a refinement of that? Is it something else altogether?
UPDATE: @mikest 's phrase “Active Damped Harmonic Motion” led to this article, which I’ll now go squint at for a long time. Thank you!
