A temperature loop continuously compares measured temperature against a target and adjusts a steam valve based on that comparison, feeding the result back into the next adjustment. This arrangement is an example of which loop type?
- A.Open-loop control
- B.Manual control
- C.Closed-loop feedback control
- D.Feedforward-only control
Why C is correct
Closed-loop control uses feedback from the measured process variable to continuously correct the output toward the setpoint. Open-loop control issues commands without using the measured outcome to adjust them.
