The "Proportional-Integral-Derivative Controller", known as PID controller, is used to balance a million things like drone motors, air contitioners, assembly line robotic arms, and chainsaws.

It can be made to work electronically, pneumatically, or mechanically.

It - and partial versions of it (like a PD Controller) - was independently invented multiple times throughout history:

  • windmills in 17th century france to regulate pressure based on wind speed
  • factory steam engines to regulate fuel consumption based on load (Centrifugal Governor - invented twice)
  • the 19th century Whitehead Torpedo to reach and maintain depth
  • tons more, I forget
