A compensation section compensates the machining command position by the compensation value obtained by the compensation value calculation section.

Abstract: In an internal combustion engine control device, a predetermined margin torque is set such that it is possible to maintain a predetermined engine idling speed by adjusting ignition timing with respect to load fluctuations during idling operation.
