Closed-loop System Identification of an HCCI Engine

Olsson, Jan-Ola LU ; Pfeiffer, Roland LU ; Tunestål, Per LU ; Johansson, Bengt LU and Johansson, Rolf LU orcid (2004)
Abstract
Homogeneous Charge Compression Ignition (HCCI) is a promising but challenging combustion engine concept. The potential for good fuel economy and low emissions is high but the transient performance required for automotive applications presents a few problems still to be solved. The focus of this work is identification of the process dynamics. An ARX type model is fitted to input-output data. A method applicable under closed-loop control is suggested and demonstrated. The resulting models are evaluated in terms of the repeatability of model characteristics, prediction accuracy, residual characteristics and comparison to spectral models is made.
