Basic Tutorial - Trend Windows, PID and Ratio Control
|IMPORTANT: The videos here supplement the SysCAD Basic Tutorial located in the install directory at SysCADxxx\Tutorial\SysCADBasicTutorial.pdf. Refer to this document for detailed instructions.|
Latest SysCAD Version: 27 August 2022 - SysCAD 9.3 Build 139.31623
Section 6 Overview
Please use these videos together with Section 6 of the Basic SysCAD Tutorial, which is distributed with the SysCAD full install.
We will continue to use the project that we have constructed and modified in the previous sections of the Tutorial.
In this section we will look at how to use Trend Windows in a SysCAD project and then add 3 controllers to the project:
- We will control the steam feed to the Autoclave to give the desired exit temperature from the Autoclave;
- We will tune the Autoclave acid feed controller (please see the Tutorial document for a description on adding this controller to the project); and
- We will control the water feed to the Autoclave to a set ratio with the solid feed to the Autoclave.
The first 2 control requirements will be achieved by using PID controllers, and for the 3rd one we will use a Set Tag Controller.
Add and Configure a PID Controller
This video shows you how to add and configure a PID Controller to control the Steam Feed to obtain the desired Autoclave discharge temperature.
Please add the Acid controller to the Autoclave project BEFORE watching this video.
