<p>A method for controlling an internal combustion engine is provided. The engine includes a variable geometry turbocharger (VGT) system and an exhaust gas recirculation (EGR) system. In a boost mode, the VGT system is controlled with a closed loop based on boost pressure. In an EGR mode, the VGT system is controlled with a closed loop based on EGR rate. Further, in the EGR mode, the EGR system is controlled with a closed loop based on boost pressure. Preferred control techniques are also provided including non-linear compensation and adaptive feed forward control.</p> |
