This is from my sister:
Do you have any other information on what she's looking for?
Here is some more info she gave me, possibly the assignment
Thanks all, this is urgent!
And this can be on any system at all? No other constraints?
Tell her to contact a local wind tunnel.
I'm pretty certain that velocity tests using pitot tubes are all done on feed forward observations. Velocity as a function of distance along the test airfoil.
Is that sort of like what she's looking for?
EDIT: I'm not sure... from the language, it sounds like she's looking for a control system type application, not a data aquisition type application. Am I wrong?
Right, I googled with +"open-loop" +"data set". Thousands of hits but no specific data sets yet
A few more possibilities:
Find a freshman physics. He must have done a few practical tests with open loop systems.
Generate a test of an open loop system yourself perhaps by measuring system response on a jump input on a simple band filter or something like that.
Separate names with a comma.
