Title:Approximate Optimal Control of the Air Path of a Diesel EngineAuthor(s):Mario Sassano,  Thomas Ernst Passenbrunner,  Markus Hirsch,  Luigi Del Re,  A. AstolfiAbstract:The problem of tracking set-point reference values for the fresh mass airflow MAF and the absolute pressure in the intake manifold MAP in the air path of a Diesel engine is considered here. To begin with, a NARX model of the air path of a Diesel engine is obtained in terms of two (coupled) difference equations from input/output measurements of the actual system. A continuous-time state-space representation of this model is then determined and used to design a control law that solves the tracking problem, achieving at the same time a criterion of optimality. To conclude the paper, the performances of the proposed control law are tested in simulation.Booktitle:Proceedings of the American Control Conference 2012Page Reference:6 page(s)Publishing:6/2012
