lets us dscribe the role of indivitual |P,|I,|D in |PID
controller....
|P(proportonal)==to give one to one correspondense between
the error signal and manipulated signal.This give linearity
between the above two signal and thus bring output varialbe
to controlled value or set point.
|I(integral)==to remove the offset error.
|D(derivative)==to fasten the control action.
