A control oriented multivariable identification procedure for turbocharged diesel engines

Under actuated air path control of diesel engines for low emissions and high efficiency

This paper presents a new method for feedback control using the Exhaust Gas Recirculation (EGR) valve and Variable Geometry Turbine (VGT) of a diesel engine. The controller effectively counteracts disturbances in NOx and PM emissions while maintaining the fuel efficiency. It is shown that by using a new combination of outputs, the controlled...
