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 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 torque (Msoll) 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 torque (Msoll); and
adapting the control rule—which is used to determine the target torque (Msoll)—as a function of at least one adaptation variable, the at least one adaptation variable being selected from a group consisting of the generator frequency (fG) which is detected, a target torque variable, and a generator power,
wherein the closed-loop control device is further configured for an open-loop control device to be operatively connected to the closed-loop control device for directly controlling the internal combustion engine, the closed-loop control device being configured for transferring the target torque (Msoll) generated as the manipulated variable to the open-loop control device.
