Which of the following is a key characteristic of closed-loop systems?

Closed-loop systems are defined by their use of feedback to monitor and adjust their operations dynamically. This feedback allows the system to compare the output to a desired setpoint and make necessary adjustments to minimize any discrepancies between them. By continuously assessing the performance of the system against the desired outcome, closed-loop systems can improve accuracy and stability in their operations.

For example, in a temperature control system, a thermostat measures the current temperature of an environment and turns the heating or cooling system on or off as needed to maintain the desired temperature. This feedback loop is essential for the precise control that closed-loop systems provide.

In contrast, systems that strictly operate without feedback tend to be open-loop systems, which do not incorporate performance data to make adjustments. While having minimal setup might describe some systems, it does not pertain specifically to closed-loop systems and can apply to various types, including open-loop configurations. Additionally, closed-loop systems are often more complex than their open-loop counterparts due to the additional components required for feedback and control, meaning that simplicity does not define them.
