Control Loop
Mechatronics & Robotics · Chemical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A control loop is the fundamental structure of a feedback control system consisting of a process, sensor, controller, and actuator. It continuously measures the output and adjusts the input to maintain the desired setpoint.
Example in context
“The engineer tuned the control loop gains to eliminate steady-state error in the temperature regulation system.”
“Mühendis, sıcaklık düzenleme sisteminde kalıcı hatayı ortadan kaldırmak için kontrol çevrimi kazançlarını ayarladı.”
Where engineers use it
Engineers work with control loops when designing feedback systems for robots, drives, and process controllers. Understanding loop dynamics is crucial for stability and performance.
Synonyms: feedback loop, closed loop
Antonyms: open loop
In Chemical Engineering
The complete chain of a sensor, a transmitter, a controller, and a final control element that together hold one process variable at its desired value. Information travels around the loop continuously as the controller reacts to measured deviations.
“Each control loop was tested during commissioning by moving the valve manually and confirming that the transmitter reading changed in the expected direction.”
