Popis:As an emissions limits of diesel vehicle became more and more
strict the control system of diesel engines become more complex and
involve usage of new technologies as aftertreatment devices such as
Diesel Particulate Filter (DPF). DPF is a device designed to remove
the diesel particulate matter or soot from exhaust flow by capturing
it on a its surface. As a surface of catalyst is limited, DPF needs to
be regenerated by increasing the inlet temperature so that the soot is
burnt and occupied surface space is made free for next cycle. As DPF
is highly nonlinear plant the application of model based control
method involves development of observer mainly for space occupied by
soot. The goal of the work would be application of Model Predictive
Control (MPC) for control of DPF. Hence the work could be split into 3
main tasks: Modeling, Observer and Controller development tasks.
Pokyny:The goal of the work would be:
1.Development of DPF Model (Matlab scripts or S-Function)
a.Existing Literature Review
b.Decision of model structure
c.Model implementation
2.Development of DPF Observer (Matlab scripts or S-Function)
a.Existing Literature Review
b.Decision of observer structure
c.Observer Implementation
3.Development of DPF MPC Controller (Matlab scripts or S-Function)
a.Existing Literature Review
b.Decision of controller strategies, sensors involved
c.Controller Implementation
