What is one advantage of a closed-loop feedback system?

Simplicity of design
Ability to react to disturbances in the system
Less stability than an open-loop system
Calibration dependency for accuracy

The correct answer is: Ability to react to disturbances in the system

A closed-loop feedback system is designed to monitor its output and make adjustments based on feedback, which allows it to react effectively to disturbances within the system. This inherent ability to adjust in real time enables the system to maintain its performance and achieve desired outcomes even when external factors or internal changes occur. For example, in an IoT application, if a sensor detects that a temperature is deviating from a set point, the closed-loop system can automatically adjust heating or cooling to bring the temperature back to the desired level. This adaptability is crucial in environments where conditions frequently change, making closed-loop systems particularly valuable in applications such as industrial automation, climate control, and robotics, where consistent performance is essential despite variable conditions. Thus, the ability to respond to disturbances distinguishes closed-loop systems from others, underscoring their advantage in maintaining stability and desired functionality.
