Abstract

An engine control system comprises a predicted airflow module, a first actuator determination module, a first desired air module, and an actuator position module. The predicted airflow module determines a predicted engine airflow based on a desired torque. The first actuator determination module determines a first engine actuator value based on the predicted engine airflow. The first desired air module selectively determines a first desired engine air value based on the first engine actuator value and the desired torque. The actuator position module determines a desired engine actuator value based on the first desired engine air value.
