This paper deals with the simplification and optimization methods in diesel engine control which is based on the air management system model of 1stage VTG and HP-EGR. Especially, simplified model based controller is suggested including more tracking performance of target values for comparison from previous multivariable sliding mode controller with intake(More)
This paper describes a pressure and flow based control method of diesel engine air-path systems equipped with dual-loop exhaust gas recirculation (EGR) and variable geometry turbine (VGT). For the control of dual-loop EGR systems, fraction states are usually controlled, but how to select the control outputs is still controversial. In this paper, considering(More)
This paper describes simplified burnt gas fraction estimation method for turbocharged diesel engine with dual loop exhaust gas recirculation (EGR) system. According to the strengthening emission gas regulation in diesel engine, burnt gas fraction has become principal factor for diesel engine air path system. Previous burnt gas fraction estimation method was(More)
