1. A closed-loop control device for closed-loop control of a power assembly including an internal combustion engine and a generator having an operative drive connection to the internal combustion engine, the closed-loop control device comprising:
the closed-loop control device which is configured, in a first functional state, for:
detecting a generator frequency (fG) of the generator as a controlled variable;
determining a control deviation (ef) as a difference between the generator frequency (fG) which is detected and a target generator frequency (fsoll);
determining a target speed (nsoll) as a manipulated variable for controlling the internal combustion engine as a function of the control deviation (ef);
using a control rule for determining the target speed (nsoll); and
being operatively connected to an open-loop control device of the internal combustion engine in such a way that the target speed (nsoll) can be transmitted by the closed-loop control device to the open-loop control device.
