control device

Abstract

This prevents the unit from failing. [Solution] A control device for an engine system comprising an engine, a unit to which vibrations from the engine are input, and a rotational speed adjustment device for adjusting the rotational speed of the engine, which controls the rotational speed adjustment device, is used in an engine system that includes an engine, a unit to which vibrations from the engine are input, and a rotational speed adjustment device for adjusting the rotational speed of the engine that contributes to the vibration of the unit, when it detects signs of failure of the unit, it sets a vibration contributing rotational speed as the rotational speed of the engine that contributes to the vibration of the unit, based on vibration influence data which is the relationship between vibrations input to the unit and the rotational speed of the engine that has been acquired in advance, and controls the rotational speed adjustment device so that the rotational speed of the engine is different from the vibration contributing rotational speed.
