Abstract

In this paper, a nonlinear control technique based on the property of flatness is proposed to control the diesel engine air system. More precisely, to achieve tracking of suitable references (corresponding to low emissions) for the air-fuel ratio and the fraction of the recirculated exhaust gas. The simulated diesel engine is a six cylinders medium duty Caterpillar 3126 B equipped with a variable geometry turbocharger and an exhaust gas recirculation valve. The proposed controller is designed on the reduced third order mean value model and implemented by endogenous linearizing dynamic feedback on the full order model. The controller is assessed through simulations with a SIL architecture using dSpace simulator. It exhibits good control performance without zero dynamics and ensures global stability and tracking of flat output references.
