Abstract
In an engine speed controlling method in a PI isochronous control mode, the initial value of an integral term for PI control is determined when the difference between a given target engine speed and an actual engine speed becomes more than a prescribed level, and the value of the integral term is change to the value of a no-load rack position at which the target engine speed is maintained in no engine load condition, when the actual engine speed becomes equal to the target engine speed, whereby large overshoot and undershoot can be effectively suppressed.
