.

Using the File menu, you can:

• Import and export models
• Save and reload sessions
• Set toolbox preferences
• Print and print to figure
• Close the SISO Design Tool

The following sections describe the File menu options in turn.

Import

To import models into the SISO Design Tool, select Import from the File menu. This opens the Import System Data window, which is shown below.

The Import System Data Window

The following sections discuss the System Name, Import from, and System Data panels of the Import System Data window.

System Name.   Use the Name field to assign a name to the imported system. The default name is untitled.

Import From.   To import models, select them from the SISO Models list and use the right arrow buttons to place the models in G (plant), H (sensor), F (prefilter), or C (compensator). You can import models from:

• The MATLAB Workspace
• A MAT-file
• Simulink (.mdl files)

System Data.   The System Data panel performs two functions:

• Feedback structure specification -- Click Other to toggle between placing the compensator in the forward and feedback paths
• Model import specification -- You can import models for the plant (G), compensator (C), prefilter (F), and/or sensor (H). To import a model, select it from the SISO model list and click the right-arrow button next to the desired model field.

Export

Selecting Export from the File menu opens the SISO Tool Export Window.

The SISO Tool Export Window

With this window, you can:

• Export models to the MATLAB Workspace or to a disk
• Rename models when exporting
• Save variations on models, including open and closed loop models, sensitivity transfer functions, and state-space representations

Exporting to the Workspace.   To export models to the MATLAB workspace, follow these steps:

1. Select the model you want to export from the Component list by left-clicking the model name. To select more than one model, hold down the Shift key if they are adjacent on the list. If you want to save nonadjacent models, hold down the Ctrl key while selecting the models.
2. For each model you want to save, specify a name in the model's cell in the Export As list. A default name exists if you do not want to assign a new name.
3. Click Export to Workspace.

Exporting to a MAT-file.   If you want to save your models in a MAT-file, follow steps 1 and 2 and click Export to Disk, which opens this window.

Choose where you want to save the file in the Save in field and specify the name you want for your MAT-file in the File name field. Click Save to save the file.

Save Session

You can quit MATLAB and later restore the SISO Design Tool to the state you left it in by saving the session. Select Save Session from the File menu. This opens the Save Session window.

To save a session, specify a file name and click Save. The current state and configuration of your SISO Design Tool are saved as a MAT-file. To load a saved session, see the Load Session section.

Load Session

To load a saved SISO Design Tool session, select Load Session from the File menu. This opens the Load Session menu.

Sessions are saved as MAT-files. Select the session you want to load from the list, and click Open. See Save Session for information on saving SISO Design Tool sessions.

Toolbox Preferences

Select Toolbox Preferences from the File menu to open the Control System Toolbox Preferences menu.

The Control System Toolbox Preferences Window

For a discussion of this window's features, see Setting Toolbox Preferences online in the Control System Toolbox documentation.

Print

Use Print to send a picture of the SISO Design Tool to your printer.

Print to Figure

Print to Figure opens a separate figure window containing the design views in your current SISO Design Tool.

Close

Use Close to close the SISO Design Tool.
