Workshop on Engine Emission Modeling for Control and Diagnostics
Sprache des Titels:
The increasing complexity of automotive systems and the high number of variants make the exploitation of available degrees of freedom increasingly difficult. Model based control is generally advocated as a solution or at least as a support in this direction, but modeling is not a simple issue, at least for some problems in automotive applications,
e.g. in emissions based control. On the one hand classical first principle methods are extremely helpful because they provide a good insight into the operation of the systems (e.g. crank angle based NOx emission model), but frequently require much effort and/or do not achieve the required precisions and/or are not suitable for online use. On the other hand there is much know-how available in the identification community to improve this, either by purely parameter estimation based approaches (e.g. nonlinear mean value NOx emission model) or by mixed models, but this know-how is frequently not tailored for the needs of the automotive community and the cooperation is quite limited.
Against this background, this workshop aims at bringing together a limited number of experts from industry as well as from academia to discuss the issue of emission modeling, in particular to determine potentials as well as limits of the different approaches, and on how the possible next steps could look like in order to enhance the research in this field.
