Final answer:
The advantage of a closed-loop feedback system is the ability to react to disturbances and maintain stability.
Step-by-step explanation:
The advantage of a closed-loop feedback system is the ability to react to disturbances in the system. In a closed-loop system, feedback is used to monitor the output of the system and make adjustments to maintain desired behavior. This allows the system to respond effectively to changes and maintain stability. For example, in a thermostat system, the temperature sensor continuously monitors the room temperature and adjusts the heating or cooling accordingly to maintain the desired temperature.
