Curious. The ancient Egyptians knew a little about negative feedback.
The earliest detailed paper on the subject of feedback control is one by
James Clerk Maxwell as far as I know. It is considered the start of
feedback control as an exact science if you will. James Watt, of course,
had used negative feedback but Maxwell studied stability. Maxwell's
paper contains the basics of feedback control that undergraduates study
today in their EE curricula. See if you can find it. It is a good read
and a lot of engineers today do not go beyond Maxwell's work when they
design opamp circuits.
