6. CONCLUSION
This work shows that the strategy proposed in Moulin
and Chauvin (2009, In Press) for gasoline engines with
fixed geometry turbines in previous publications can be
extended to more complex architectures with variable
geometry turbines, while taking into account interactions
with other subsystems in the form of constraints.
The turbocharger control strategies designed from this
model combined with an adequate EGR control and estimation
provide a solid basis for the management of modern
Diesel engines. In particular, the calibration of a complex
air system could be a daunting task. In the proposed
structure, the effort required is greatly reduced thanks to
an adequate physical representation of the system.
