Which system is defined as one that adjusts outputs based on feedback from those outputs?

A system that adjusts outputs based on feedback from those outputs is known as a closed-loop system. This type of system continuously monitors the output and compares it to a desired setpoint, making adjustments when discrepancies occur. The feedback mechanism is essential, as it enables the system to respond to changes in the environment or in the process itself, ensuring that the output remains consistent and within the desired parameters.

In contrast, open-loop systems do not utilize feedback to control their outputs; they operate under predetermined settings without altering their operations based on the results. Simple loop and static loop systems do not accurately describe the feedback mechanism characteristic of closed-loop systems. Thus, the definition of a closed-loop system aligns precisely with the description provided in the question, highlighting its reliance on feedback for output adjustment.
