Create a Simulink Model

R2026b

Create a simple model of a damped square-wave generator. You can use this model as an example to learn other capabilities that are useful with Simulink^® Desktop Real-Time™ software.

1. In the MATLAB^® Home tab, click the Simulink button.

2. Hover over the Blank Model or open the Simulink Desktop Real-Time group from the template groups and hover over a model template, and then click Create Model.

   An empty Simulink Editor opens.

3. On the Simulation tab, click Library Browser.

4. In the Library Browser:

   • Select Simulink > Sources, and then add a Signal Generator block to the model.

   • Select Simulink > Continuous, and then add a Transfer Fcn block to the model.

   • Select Simulink > Sinks, and then add a Scope block to the model.

5. Make the following block-to-block connections:

   • Signal Generator output to Transfer Fcn input

   • Transfer Fcn output to Scope input

6. Double-click the Transfer Fcn block. The Block Parameters dialog box opens. In the Numerator text box, enter:

   [10000]
   

   In the Denominator text box, enter:

   [1 70 10000]
   

   Click OK.

   

7. Double-click the Signal Generator block. From the Wave form list, select square.

   In the Amplitude text box, enter:

   1

   In the Frequency text box, enter:

   20

   From the Units list, select rad/sec.

   Click OK.

   

   The completed Simulink block diagram looks like the figure.

   

8. In the Simulink Editor, on the Simulation tab, click Save > Save as. In the File name text box, enter a file name for your Simulink model and click Save. For example, type:

   sldrtex_model
   

   The Simulink software saves your model in the file sldrtex_model.

The Simulink Desktop Real-Time software supports model referencing. See Model Reference Behavior and Capabilities.

The Simulink Desktop Real-Time software supports file I/O, with constraints. See File System I/O.

To specify a default Simulink Desktop Real-Time configuration set for your model, see Specify a Default Configuration Set. If you activate this configuration set for your model, you can build your real-time application later without setting additional configuration parameters.

To configure your model manually, see Enter Configuration Parameters Manually.
