Physical Model Based Control of the Airpath of Diesel Engines for Future Requirements

Keywords: boost pressure control, EGR-control, model based, decoupling, inverse models

The gas exchange system of modern diesel engines and its control has to fulfill increasingly challenging requirements in order to further reduce raw emissions with regard to the next legislations in the main markets, improve torque and dynamic response over the whole speed range and to support exhaust aftertreatment systems. The introduction of the physical model based control of the airpath gives the possibility to reduce lookup table structures, to adjust to changing operation conditions as well as linearization, disturbance compensation and decoupling of control loops.
