www.controlglobal.comFigure 3. Closed loop flow rate control of Natural Gas Liquids through a control valve into a depropanizer column. The PID controller executes in a DCS. The process model is self-regulating first order plus dead time. The dead time (occurring both in open loop and closed loop) is mostly due to nonlinearity in the response of the control valve.
Introduction to PID Control - Sharif
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
