Process of control-cybernetic control model

Good afternoon,
I understand that cybernetic control model describes the process of control and has the following key stages:
-objective identification
-setting targets
-measuring outputs
-comparing outputs with targets
-identifying corrective action
-implementing corrective action
My question is are there some real life examples of the so called cybernetic control model that i can relate to? If so what are they and is there a need for me to know them for exam purposes.
