Answer Posted / md. jawed akhtar
In open -loop control system, the input has no control over
output variable.
where as in close-loop(or feedback)control system,the input
has control over output variable.In this system,the variable
output is measured and feed to the controller through path(or
loop).In controller compares the desire reference value with
the actual value and acts to reduce the difference between the
two to zero value.
