|Abstract: ||In this paper, two types of dynamic model for
automotive diesel engine fuelled with palm biodiesel
(Palm Oil Methyl Ester) are being developed using a
black box technique. Assuming a discrete time form for
the system model, an Autoregressive with eXogenous
input (ARX) and an Autoregressive Moving Average
with eXogenous input (ARMAX) model structures were
selected in this work. The models are derived for the
development of real-time self-tuning speed controller
purposes. Real-time input-output data obtained from a
2.0L automotive diesel engine with test-bed unit were
used for modeling. A Pseudo-Random Binary Sequence
(PRBS) with maximum lengths sequence of 31 has been
used as the input signal to determine the dynamic models
of automotive palm biodiesel engine for medium speed
range around 2100 rpm. The input and output signals
were interfaced to the plant via Matlab programming.
Recursive estimation algorithms, Recursive Least
Squares (RLS) and Recursive Extended Least Squares
(RELS), were used to estimate the parameters of each
model. Finally, model validation was done by plotting
the output predicted by the model and comparing it with
the measured output.|
