PID Controller Tuning in Aspen HYSYS - The Ziegler Nichols Method (Open Loop Tuning)

This tutorial elaborates on how to do tuning of a PID controller in Aspen HYSYS. If you need the HYSYS file used in this tutorial, email me. It explains how to record and retrieve historical data from a controller in HYSYS. Different methods such as Ziegler Nicholas, Cohen-Coon, and ITAE can be used to tune a controller. In this tutorial, I have used the Ziegler Nicholas method to tune a flow controller.
