ee.sharif.eduProportional-Derivative control Now, let's take a look at a PD control. From the table shown above, we see that the derivative controller (Kd) reduces both the overshoot and the settling time. The closed-loop transfer function of the given system with a PD controller is: Let Kp equals to 300 as before and let Kd equals 10. Enter the
