Abstract
An engine control system includes a power module, an air flow module, a torque estimation module, and an air control module. The power module determines a power-based torque based on a desired engine speed. The air flow module determines an air flow value based on the power-based torque. The torque estimation module estimates a desired torque based on the air flow value. The air control module selectively determines a throttle area based on the desired torque. A throttle valve is actuated based on the throttle area.
