The best way to learn is to fail. Aka, experiment.
Also,
http://team358.org/files/programming...2009-/LabVIEW/ that was posted above, was a great resource for me when I was learning Labview (halfway through a season!). Try mixing some of their examples together and like I said, experiment.
Make a testbed with a basic control system, with a few different kinds of motors, relays, and sensors, so you can test out your code.
Good luck
