This control device calculates a steady-state target value that is the target value of supercharging pressure during a steady operation on the basis of the engine RPM and fuel injection quantity, and operates an actuator by feedback control such that the actual supercharging pressure calculated from the signal of a supercharging pressure sensor approaches the steady-state target value. However, when any condition among a plurality of different conditions that are likely to be met during a transient operation is met, the transient target value of supercharging pressure suitable for the met condition is calculated in accordance with a calculation rule prepared for each of the conditions. On this occasion, if one transient target value is present, this transient target value is selected, and if a plurality of transient target values are present simultaneously, one transient target value is selected in accordance with priorities determined according to acceleration. Then, the target value of feedback control is changed from the steady-state target value to the selected transient target value. |
