What is a primary characteristic of a Closed Loop System?

A primary characteristic of a closed-loop system is that it uses real-time sensor information to monitor the system's performance and make adjustments as needed. This capability allows the system to continually compare actual outputs to desired outputs, which enhances its accuracy and stability over time. By incorporating feedback, the system can correct deviations from the desired performance, adapt to changes in the environment, and improve overall efficiency.

In contrast, a system that operates with complete independence from feedback lacks the ability to self-correct and respond to changes, which is a defining feature of open-loop systems. Operating solely on pre-set inputs means that the system cannot adapt or respond to input variations, which also disqualifies it from being classified as a closed-loop. Finally, requiring user intervention to adjust indicates a lack of automated feedback control, further distinguishing it from closed-loop systems that are designed to operate with minimal manual input.
