Background

Tunable Block Parameters and Tunable Global Parameters

Changing tunable block parameters and tunable global parameters during real-time execution.

Parameter Tuning

Tune Parameters with MATLAB Language

Change block parameters while your real-time application is running on the target computer.

Tune Inlined Parameters with MATLAB Language

Tune inlined parameters that have been made tunable with MATLAB variables.

Tune Parameter Structures with MATLAB Language

Organize related parameters into a structure and use the structure to tune parameters.

Save and Reload Parameters with MATLAB Language

Save real-time application parameter values to a file on the target computer.

MATLAB Interface

Real-Time Application Objects

Use the MATLAB Command Window to change properties and control the target computer and your real-time application.

Limitations

Troubleshoot Parameters Not Accessible by Name

Investigate issues that prevent you from observing or tuning some parameters in the real-time application.

Troubleshoot Instance-Specific Parameters Not Saved

Investigate issues that prevent saving instance-specific parameters and parameters with custom storage classes to a MAT file.

Troubleshoot Instrument Label Not Present

Investigate issues that produce error 'The given key was not present in the dictionary' for instrument labels.

Parameter Tuning and Data Logging

Parameter Tuning and Data Logging

Do real-time parameter tuning and data logging with Simulink® Real-Time™. After the script builds and downloads the oscillator model, xpcosc, to the target computer, it makes multiple runs with the gain 'Gain1/Gain' changed (tuned) before each run. The gain is swept from 0.1 to 0.7 in steps of 0.05. The parameter index of 'Gain1/Gain' is retrieved from the Simulink Real-Time target object using the function GETPARAMID.
