Tune Block Parameters by Using the Block Dialog Box

Step 1 of 3 in Tunable Block Parameters and Tunable Global Parameters

After running your real-time application, use the block mask dialog box or Property Inspector to change parameter values and observe the changes to the signals. In Connected IO mode or accelerator mode, Simulink^® transfers the new values to the model that is being simulated. In Run in Kernel mode, Simulink transfers the new values to the real-time application that is running in the kernel mode process.

For this example, your goal is to minimize ringing in the transfer function.

This procedure begins with the square-wave transfer function model sldrtex_model. To open this model, in the MATLAB^® Command Window, type:

openExample('sldrtex_model')

This model opens in Connected IO mode.

First, install the Simulink Desktop Real-Time™ kernel and cd to a working folder.

1. Open sldrtex_model.

2. Open the Scope block.

3. In Simulink Editor, on the Desktop Real-Time tab, select Mode > Run in Kernel.

4. On the Desktop Real-Time tab, select Run in Real Time > Stop Time and change the Stop Time to Inf.

5. On the Desktop Real-Time tab, click Run in Real Time. Simulink builds the real-time application, connects to the real-time kernel, and starts running the real-time simulation.

   

6. Open the Transfer Fcn block parameters dialog box.

7. Change Denominator coefficients to [1 180 10000].

   

8. Click Apply.

   

9. On the Desktop Real-Time tab, click Stop.
