<p>PURPOSE:To aim at improvements in control responsiveness and control accu racy, by calculating a learned value according to the integrated value of a deviation between the actual supercharging pressure and the control desired value and the discriminating result of a running range. CONSTITUTION:A deviation operational device 7 calculates a deviation between the detected supercharging pressure and the desired supercharing pressure. A controlled variable operational device 3 calculates the controlled variable corresponding to at least either of an exhaust turbine displacement variable device 6 or an exhaust bypass valve on the basis of a running state. A feedback compensating device 4 compensates the controlled variable for feedback according to an integrated value of the deviation. A control device 5 controls at least either of the displacement variable device 6 or the exhaust bypass valve according to the controlled variable. A learning operational device 9 calculates a learned value of at least either of the displacement variable device 6 or the exhaust bypass valve according to the discriminating result of a running range out of a running range discriminating device 8 and the integrated value of the deviation.</p> |
