Answer / jagadeesh

if the error is reduced by increasing or decreasing the
duration then it is known as integral controller and if the
error is redued with respect to the rate then it is known
as derivative controller.

Answer / gonzales

Answer given by Gnv207 very confusing

Answer / rizwan

In simple u can say

Proportional----how much controller will open or close

Integral---how long it will keep the same controller opening

Derivative----how fast controller will complete its action

Answer / mohammed emaaduddin

In Integral control, the value of o/p at any given time is the integral of the error over that period of time.
In derivative control, the o/p is proportional to the derivative of the error..

Answer / gnv207

The actual error is directly proportional to the integral
value of the error ,that type of control is called as integral
control.

The same manner the derivative control is

The actual error is directly proportional to the derivative
value of the u(t)error ,that type of control is called as
integral control.
