Characteristic and step response of the D component of a PID controller
D component
Function: Y = Kd d Xd/dt
Kd is the differential action factor. The greater Kd, the stronger the D influence.
Characteristic
A controller with a D component reacts to changes in the controlled variable and can thus reduce more
quickly any control differences that occur.
