Abstract :
In this paper, a third order nonlinear model of the airpath of a turbocharged diesel engine is derived, which is then converted into linear parameter-varying (LPV) form with the intake and exhaust manifold pressure as parameters. The model predicts the mass air flow (MAF) and manifold absolute pressure (MAP) based on the EGR and VGT actuator positions, speed, and load. A comparison to experimental data from the engine test bed and to a higher order nonlinear model suggests the validity of this approach.
