1. try to maintain X psi of boost
if boost > X, open vanes unless fully opened
if boost < X, close unless fully closed
2. if exhaust pressure too high, open vanes even if boost < X
3. if egt too high, fully open vanes, sound alarm
For optimal fuel economy, and if you have gobs of free time, the ideal thing to do would be to calculate engine load and only generate enough boost needed for that load. That would require LOTS of tuning though.
