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.
