In a closed-loop system, what is the purpose of feedback?

Step 1: Understand that a closed-loop system is a system that uses feedback to control its output.
Step 2: Identify that feedback is information about the actual output of the system.
Step 3: Recognize that the desired output is the target or goal that the system aims to achieve.
Step 4: Realize that feedback compares the actual output to the desired output.
Step 5: Learn that if there is a difference between the actual output and the desired output, adjustments are made to correct it.
Step 6: Conclude that the purpose of feedback is to ensure the system can reach and maintain the desired output.
