Abstract
Methods, devices, and/or systems for controlling intake to and/or exhaust from an internal combustion engine. An exemplary method for controlling intake charge pressure to an internal combustion engine includes determining one or more control parameters based at least partially on an intake charge target pressure; and outputting the one or more control parameters to control an electric motor operatively coupled to a compressor capable of boosting intake charge pressure and to control a variable geometry actuator capable of adjusting exhaust flow to a turbine.
