Abstract
Next generation heavy-duty diesel engines require tight air
path control to meet upcoming emission legislation with
minimal fuel consumption. This study concentrates on the
emission control of a 13l, 360 kW EGR diesel engine,
which is compliant with EPA2010 emission targets. Currently,
an input-decoupled controller design is often applied
for EGR-VTG control. The performance of such a state-ofthe-
art controller is compared with an SVD-decoupled control
design and time optimal control. All three controllers
use a newly introduced control parameter: exhaust oxygen
concentration. For disturbances around an engine operating
point, the performance of these controllers is evaluated
from simulation results. Especially, settling time and NOx
and PM emissions are of interest. A comparison is presented
which shows that SVD-decoupled control will give
improvements over input decoupled control in terms of performance
and simplicity. Time optimal control shows that
further improvements of settling times are possible, but the
required large control inputs will have a significant effect
on the produced torque.
