From what I understand:
Goal: Create a practical electric supercharger.
Questions:
1. Do we want to control the motor speed independent of engine conditions? (like a a variable-speed trigger on the steering wheel)
2. If that's not it, what exactly do we intend to control? Might it be... intake pressure with respect to engine rpm?
a fixed intake pressure irrespective of engine rpm?
intake pressure with respect to throttle position?
intake pressure with respect to both engine rpm and throttle position?

People have different goals. Most of us want a more sophisticated control system that at the very least uses throttle position. Other options are boost, RPM, or all three.
I'm personally using a Unichip tuning module right now in my test setup which allows me to create a map based on engine RPM and throttle position.
The Phantom Electric Super Charger simple uses a switch connected to the accelerator peddle that turns on when the accelerator is pressed far enough. Rob has also implemented som additional control to allow for drag reduction that pluses the motor on and off to maintain a specifics pressure.
