3 Designing Controllers Using the Design Tool GUI
3-6
Note Once you leave this view, if you subsequently change a signal type, you will have
to restart the design. Be sure the signal types are correct at the beginning.
• The Description and Unit entries are optional. You can enter the values shown in
Model Predictive Control Toolbox Design Tool's Signal Definition View manually. As
you will see, the design tool uses them to label plots and other tables.
• The Nominal entries are initial conditions for simulations. The design tool default is
0.0.
Navigate Using the Tree View
The tree in the left-hand frame of Model Predictive Control Toolbox Design Tool's Signal
Definition View shows that the default MPC Design Task node (see Model Predictive
Control Toolbox Design Tool Initial View) has been renamed CSTRcontrol by clicking
the name, waiting for the usual edit box to appear, typing the new name, and pressing
Enter to finalize the choice.
Model Predictive Control Toolbox Design Tool's Signal Definition View also shows three
new nodes below CSTRcontrol. These activate once you've imported a plant model (or
controller).
In general, clicking a node displays a view supporting a particular design activity.
Project View (Signal Properties Tables)
For example, clicking the project node (CSTRcontrol in Model Predictive Control
Toolbox Design Tool's Signal Definition View) allows you to review and edit the signal
properties tables.
Listing Your Plant Models
Select the Plant models node to list the plant models you've imported, as shown in
Plant Models View with CSTR Model Selected. (Each model name is editable.) The
Model details section displays properties of the selected model. There is also a space to
enter notes describing the model's special features. Buttons allow you to import a new
model or delete one you no longer need.
