Abstract
A method for controlling intake airflow in an internal combustion engine including an intake air compressor includes determining a first compressor boost signal based upon a predetermined intake manifold pressure command, determining a second compressor boost signal based upon a predetermined exhaust pressure limit, determining a compressor boost control command based upon the first compressor boost signal and a limit comprising one of a maximum boost setting and said second compressor boost signal, and controlling the intake air compressor in response to the compressor boost control command.
