Definition:

linear time-invariant transfer element the time derivative of the output variable of which is proportional to the corresponding value of the input variable

Note 1 to entry: The transfer function of an I element is given as

$\frac{V (s)}{U (s)} = \frac{K_{I}}{s}$

where

K_I is the integral action coefficient;

s is the complex variable of the Laplace transform;

U(s) is the input transform;

V(s) is the output transform.
