Abstract :
The aim of this paper is to present an identification procedure for NARX models describing the pressure inside the intake manifold and the crankshaft speed of Internal Combustion (IC) car engines. The proposed method is based on a stepwise regression approach and has been applied to real data collected on two commercial engines, namely a 1600cm3 and a 1200cm3. A number of experimental results witness the applicability of the proposed approach.
