Added some open-loop experimental data.

software/quanser_work/data/README.md

+# Data sets from experiments
+
+## Open-loop experiment
+
+Here we provide the data from the open-loop experiment `software/quanser_updated/q_as_ol.slx`. 
+Load the data into Matlab workspace using
+
+```matlab
+load measured_and_simulated_open_loop_responses.mat
+```
+
+Two new data structs then appear in the workspace
+ 
+- `measured_ol_response`
+- `simulated_ol_response`
+
+Plot these using
+
+```matlab
+figure 
+plot(measured_ol_response.time, measured_ol_response.signals.values)
+figure
+plot(simulated_ol_response.time, simulated_ol_response.signals.values)
+```
+
+See the corresponding Simulink file for the meaning of the stored variables.
