Importing and Exporting Models

The SISO Design Tool provides graphical user interfaces to facilitate importing and exporting of linear models.

Importing Models

To import models into the SISO Design Tool, select Import under the File menu. This opens the Import System Data window.

To import a model:

• Specify whether you want to import a SISO model from the MATLAB workspace, a MAT-file, or from a Simulink model. The window lists the available models for each format under SISO Models.
• Click on the desired model.
• Press a right arrow to specify whether you want to import the model as the plant (G), Sensor (H), Prefilter (F), or Compensator (C).

• Press the OK  Button

Alternatively, you can directly import a model into the SISO Design Tool using the sisotool function, as in

• sisotool(modelname) 
  

In this case, modelname is imported as the plant (G).  See the sisotool function for more information.

Exporting Models

Use Export in the File menu to open the SISO Tool Export window.

Selecting Models to Export.   The SISO Tool Export window not only lists all the models displayed in your SISO Design Tool, but also contains various transfer functions associated with standard control analysis techniques. These include open and closed loop transfer functions, input and output sensitivity functions, and the state-space model of the overall feedback loop.

To select a model for export, left-click on the row containing the component name.  To specify a different export name, double-click on the Export As cell for the component. This makes the name in the cell editable.

You can export models back to the MATLAB workspace or to disk. In the latter case, the models are saved in a MAT-file.

Exporting to Workspace.   To export models  to the MATLAB workspace, simply press Export to Workspace.

Exporting to Disk.   If you choose Export to Disk, this window opens.

The Export to Disk window provides a default file name. If you want to change the name, specify the new name for your model(s) and press Save. Your models are stored in a MAT-file.

Exporting Multiple Models .   There are two ways to export multiple models:

• If the models are adjacent in the model selection list, hold down the Shift key while selecting the models with your mouse.
• If the models are nonadjacent, hold down the Ctrl key and select the models by left-clicking
