That sounds like your feedback is opposite of your control. Use the "invert sensor" option. (I don't have LabVIEW available at the moment, so I don't know exactly what it's called in the example.)
If you don't have much load on the motor or inertia in the system, you will find it to be very difficult to get it to stabilize. If you can limit the motor power's rate of change, doing it will help a lot.
