Section 6 Overview
Please use these videos together with Section 6 of the SysCAD Introductory 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 water feed to the Autoclave to a set ratio with the solid feed to the Autoclave.
- 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
For the first control requirement, we will use a Set Tag Controller. The remaining two control requirements will be achieved using PID controllers.
NOTE:
- In the following sections, the section number displayed alongside the videos have been updated to align with the latest tutorial documentation. These may not correspond with the original document used to create the videos.
