Abstract: The use of diesel engine turbochargers is increasing today, as it represents an option that
o ers high e ciency and low fuel consumption. To design the control system in order to
reduce the level of exhaust emissions there is a need for information about all states that
are not measurable. To this end, observers or virtual sensors are more frequently applied,
achieving estimates of the system states from inputs and measured output.
To propose an observer, the precise mathematical model of the air path diesel engine
system is used. This is a nonlinear model of a third order which is analyzed in terms
of observability. From the point of view of systems theory, certain conditions and the
existence of a transformation of the system state, called di eomorphism, need to be
evaluated.
Observers have been designed based on di erent approaches: Extended Luenberger
Observers, High Gain Observers, Sliding Modes Observers and Extended Kalman-Bucy
Filters. They have been validated by simulation for the system under consideration in
this work.
