PURPOSE:To approximate the number of rotation of an engine to a target number of rotation after an external load is applied to the engine by determining the amount of anticipatory correction for controlled variables in response to the difference between a target engine-speed after an external load is applied and an actual engine-speed immediately before the external load is applied. CONSTITUTION:A control device 15 is provided with an engine idling state detecting means 22, an engine-speed detecting means 16, external load detecting means 18-20, an engine-speed adjusting means 10 and a controlling means 23 which performs a feedback control on the engine speed at the time of idling, and changes a target engine-speed when an external load is applied, and at the same time, makes an anticipatory correction for controlled variables. In addition to the above constitution, there is provided an anticipatory correction- amount determining means 24 for determining the amount of anticipatory correction in response to the difference between a target engine-speed after an external load is applied and an actual engine-speed immediately before the external load is applied. Thereby, the engine speed can be approximated sufficiently to a target number of rotation after an external load is applied to the engine.
