Convert dSPACE ControlDesk measurement to MATLAB timeseries that can be used in Simulink

(Updated version here)

• 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:

>> import_dspace_mat_to_simulink_ts
--Imported dSPACE mat file 
C:\Users\Nicolai\Nextcloud\foo.mat
into workspace variable dsp_ts
--Time: 0.000000 s to 42.399572 s, 423980 steps
--2 variables are in dsp_ts:
 'In1' 'In1_1'

% dspace mat export to timeseries that can be used with 'From
% Workspace' in Simulink

[filename, path] = uigetfile('*.mat', 'Select dSPACE mat file');
dspace_file = fullfile(path, filename);

dspdata = importdata(dspace_file);

% name of workspace var for simulink
ts_import = struct();

ynames = {dspdata.Y.('Name')};
ynames = matlab.lang.makeUniqueStrings(ynames);

dsp_ts = [];
for i=1:size(dspdata.Y, 2)
    varname = strcat('dsp_', ynames{1,i});
    ts = timeseries(dspdata.Y(i).Data, dspdata.X.Data, 'Name', varname);
    dsp_ts = [dsp_ts; ts]; % not efficient
end

fprintf('--Imported dSPACE mat file \n%s\ninto workspace variable dsp_ts\n', dspace_file);
fprintf('--Time: %f s to %f s, %d steps\n', dspdata.X.Data(1), dspdata.X.Data(end), length(dspdata.X.Data));
fprintf('--%d variables are in dsp_ts:\n', length(dsp_ts));
disp(ynames);
