Describe the major elements of the feedback loop and how they operate to control behavior
What will be an ideal response?
The feedback loop's input function is its perception of the way things are. The comparator checks this perception against a reference value, assessing whether the perception and reference value are the same or not. If they are NOT the same, the result is an output (or a change in output). The output is aimed at reducing the discrepancy between perception and reference value.
