Description
Defines the proportional gain (K
high a gain may cause speed oscillation. The figure below
shows the speed controller output after an error step when
the error remains constant.

If gain is set to 1, a 10% change in error value (reference -
actual value) causes the speed controller output to change by
10%, ie. the output value is input × gain.
