Definition:

linear time-invariant transfer element created by the additive combination of a proportional element and a derivative element

Note 1 to entry: The transfer function of an ideal proportional plus derivative element is given by

$\frac{V (s)}{U (s)} = K_{Ρ} \cdot (1 + T_{d} \cdot s)$

where

T_d is the rate time;

s is the complex variable of the Laplace transform;

U(s) is the input transform;

V(s) is the output transform.
