feedback control
Output-adjusting system loop
Feedback control is a system that adjusts its operation based on measuring its own output.
A thermostat uses feedback control—it checks the temperature and turns heating on or off accordingly.
The principle appears throughout engineering, biology, and management: The body uses feedback control to regulate blood sugar.
Contrast with open-loop systems that operate without monitoring results.
