Abstract
An engine system includes an engine having an intake manifold and a supercharger that supplies compressed air to the intake manifold. An engine control module calculates a desired pre-supercharged pressure of air into the supercharger and calculates a desired manifold air flow into the engine. The engine control module determines a desired throttle area based on the desired pre-supercharged pressure and the desired manifold air flow and generates control signals to control the engine based on the desired throttle area.
