<p>PROBLEM TO BE SOLVED: To provide an engine control device for properly controlling an EGR adjusting device and a supercharger adjusting device.SOLUTION: An engine control device calculates control amounts to correction amounts of target exhaust pressure of the EGR valve and the turbocharger based on deviation between a target value and an actual value detected by a sensor for a fresh air amount, an intake pressure and an exhaust pressure. The engine control device calculates the control amount to the EGR valve by F/B controllers C11, C21, C31 based on the deviation between the target value and the actual value for the fresh air amount, the intake pressure and the exhaust pressure, calculates the control amount to the turbocharger by the F/B controllers C12, C22, C32, and calculates the control amount to the correction amount of the target exhaust pressure by the F/B controllers C13, C23, C33. An F/B gain is set for every controller.</p> |
