Definition:

for a proportional plus derivative element the input and output variable of which are of the same kind the duration of the time interval required by the ramp response to reach twice the value that occurred immediately after the ramp was applied

Note 1 to entry: The rate time is given by

$T_{d} = \frac{K_{D}}{K_{Ρ}}$

where

K_D is the derivative action coefficient;

K_P is the proportional action coefficient;

T_d is the rate time.
