Convert dSPACE ControlDesk measurement to MATLAB timeseries that can be used in Simulink
- dSPACE ControlDesk can export measurements to mdf4 files or mat files
- mat file exports can be converted to timeseries with this MATLAB script
- The timeseries can then be imported into Simulink with the ‘From Workspace’ blog
- Multiple signals can be imported at once
Example output:
