What type of system uses feedback to constantly adjust its operations?

A closed loop system is one that utilizes feedback to continuously monitor and adjust its operations. This means that the system measures its output and compares it to a desired setpoint, making real-time adjustments to ensure the output remains within acceptable limits. This feedback mechanism is essential for maintaining stability and accuracy in processes, particularly in applications such as heating, cooling, or regulating pressure and flow.

In contrast, open loop systems operate without feedback, meaning they do not adjust based on the output. They perform tasks based purely on predefined settings without any self-correction. Static systems, on the other hand, do not involve any movement or change, thus lacking the ability to adjust operations. Dynamic systems can change over time but may not necessarily include feedback mechanisms. Therefore, the defining characteristic of a closed loop system — the use of feedback for constant adjustment — accurately describes its capability to maintain desired operational parameters effectively.
