Abstract
A torque control system for regulating operation of an engine includes a throttle that regulates air flow into the engine and a device that regulates a torque output of the engine. A first module determines a throttle area based on a desired manifold absolute pressure (MAP) and a desired manifold air flow (MAF) and a second module determines a device set-point based on a desired air per cylinder (APC) and an engine speed. A third module generates a throttle control signal to control the throttle based on the throttle area and generates a device control signal to control the device based on the device set-point.
