Negative Feedback Loop
Updated 2026-08-17
INTRODUCTION
English translation pending.
CORE DEFINITION
A regulating loop in systems theory: the system measures its actual state against a goal, and any gap generates a corrective force opposite in direction to the deviation, driving the state back toward the target. The key qualifications are that negative here means stabilizing rather than harmful, and that loop gain trades speed against overshoot. Thermostats, blood glucose regulation, and budget control are standard instances.
SCAFFOLDING EFFECT
Reduce cognitive load
- Deviation detection: define the target and measure the actual state so the gap becomes visible. - Correction design: build a force that opposes the deviation and scales with its size. - Stability tuning: set gain high enough for speed but low enough to avoid oscillation.
Anchor fast decisions
The loop couples sensing to actuation in the opposite direction of the error. As deviation grows, so does the correcting force, which returns the state toward the goal; higher gain shortens the recovery but risks overshoot and oscillation, so stability and responsiveness must be balanced.
