Original Abstract Submitted
Provided is a control device for an internal combustion engine capable of realizing an operation of the internal combustion engine in a state in which a dilution is close to a limit. A processor (CPU ) of a control device for an internal combustion engine calculates a change amount of a parameter (for example, a combustion center position) indicating a combustion state of the internal combustion engine (combustion center change amount calculation unit ). The processor (CPU ) corrects an operation amount of an actuator (for example, an EGR valve) that adjusts a dilution of an air-fuel mixture according to a difference between the change amount of the parameter indicating the combustion state and a target value of the change amount, and brings the change amount close to the target value (actuator operation amount correction unit ).
