ABSTRACT:
A method of controlling an engine speed for an internal combustion engine and an apparatus therefor which are capable of significantly improving transient response characteristics and controlling the engine speed with high accuracy. The method and apparatus are adapted to keep the actual engine speed at a set engine speed by proportional control action and derivative control action wherein a derivative control engine speed range is set about the set engine speed to stop derivative action to allow only proportional action to operate an engine speed adjusting operation unit when the actual engine speed is out of the range.
