Closed-Loop Control
Mechatronics & Robotics · Last updated: July 30, 2026 · How this entry was written
Definition: A control strategy in which the measured output is fed back and compared with the reference, and the resulting error drives the controller. This feedback lets the system reject disturbances and tolerate imperfect knowledge of the process.
Example in context
“Once the encoder was wired in, the robot joint moved under closed-loop control and returned to the taught position despite the extra payload.”
“Enkoder bağlandıktan sonra robot eklemi kapalı çevrim kontrol altında hareket etti ve ek yüke rağmen öğretilen konuma geri döndü.”
Where engineers use it
Closed-loop control underpins servo drives, temperature regulation, and flight stabilisation. Engineers apply it whenever disturbances or model errors would otherwise ruin accuracy, and they must tune it carefully because feedback can also cause instability.
Synonyms: feedback control
Antonyms: open-loop control
Practice: can you use “Closed-Loop Control” at work?
A technician is asked to explain why a heater running under closed-loop control still reaches setpoint when a window is opened, and to sketch the signal path from sensor to actuator.
Show a model answer
“We switched to closed-loop control so the error is corrected continuously.”
