Theory 47/Feedback loops stabilise
Gain Produces Overshoot
The claim
High feedback gain produces overshoot and oscillation even without delay, because the response exceeds the disturbance.
01Mechanism
Correction proportional to error overshoots when it arrives faster than the error resolves.
02Prediction
Overshoot should rise with gain.
03Refutation
Monotonic settling with gain would remove the overshoot.
