Answer / naveed ahmad
In controller must be used proportaional (P). according to
change in input it 'll change the output. means output is
proportional to the input. if controller is direct action
it 'll be directly proportional and if controller is
reverse action then it 'll be inverslly proportional. Keep
in your mind controller input is always an error signal.

maintain a pertucular level of the system proportional is
used.
