Model based control of particulate filter regeneration (English)
Abstract [en]

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers’ mode of operation. Basedon this approach an IMC controller and a PI controller with a combined feedforwardterm are developed and analyzed. Both controllers show good performance in termsof robustness and reference tracking. The authors' firm opinion is that controlstrategies with the exhaust gas mass flow as a scheduling variable is suitable forkeeping control of the temperature in the particulate filter during regeneration.
