    Abstract: This paper investigates the design of modelbased feedforward compensators for exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT) systems using air path models for a commonrail direct injection (CRDI) diesel engine to cope with the nonlinear control problem. The modelbased feedforward compensators generate setpositions of the EGR valve and the VGT vane to track the desired mass air flow (MAF) and manifold absolute pressure (MAP) with consideration of the current engine operating conditions. In the best case, the rising time to reach 90% of the MAF setpoint was reduced by 69.8% compared with the lookup table based feedforward compensators.
