[0014] The following description relates to systems and methods for pressure control in boosted engine systems. figure 1 An example engine boosting system including a variable geometry turbine (VGT) and exhaust gas recirculation (EGR) system is shown. The opening of the VGT and EGR valves can be feedback-controlled by the engine controller based on multiple input signals including intake and exhaust manifold pressures, engine speed, and fueling schedule, such as figure 2 is shown in the example control system of . In addition to PI controllers (proportional-integral controllers), such as image 3 As shown, a gain-scheduled PD (proportional-derivative) controller can be used to further adjust the VGT vane position based on engine speed, exhaust manifold pressure, and the difference between exhaust and intake manifold pressure (△ pressure) At least one of , wastegate valve position and EGR valve opening. The engine controller can be configured to execute control programs suc...
