This talk presents the design and application of a robustly gain scheduled controller based on a third order linear parameter-varying (LPV) model of the airpath of the turbocharged diesel engine under investigation. This model-based control design reduces the calibration effort significantly (a major task that the automotive industry has to face these days), while achieving the same performance as the fully calibrated engine controller. This is accomplished by using the intake manifold air pressure as scheduling variable. A second parameter adjusting the gain of the controller is introduced to render it calibratable while the robustness guarantees still hold. After some online tuning of this single parameter, the model-based airpath controller achieves the same performance as the fully calibrated controller from the engine control unit.
