A control system to regulate water for irrigation
comes to mind, with a flow/level measurement and balance to regulate water diversion into
ditches. ?That probably goes back 500 - 1K years earlier.
Well, you could say a caveman with a fire is also a feedback control
system - Og is cold, so he adds more wood. Og is warm, so he relaxes.
History is just one big grey area.
