Abstract
In a method of controlling rotational speed for an internal combustion-generator unit, a filtered rotational speed is monitored with respect to rotational speed oscillations. When such oscillations are detectd, their frequency is compared with a first limit value, and as a function of the comparison, a first mode or a second mode is set. In the first mode, the filter is altered and, in the second mode, parameters of a rotational-speed controller are adapted to eliminate the oscillations.
