15 Claims

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 power (P_G) of the generator as a controlled variable;

determining a control deviation (e_P) as a difference between the generator power (P_G) which is detected and a target generator power (P_soll);

determining a target speed (n_soll) as a manipulated variable for controlling the internal combustion engine as a function of the control deviation (e_P);

using a control rule for determining the target speed (n_soll); and

being operatively connected to an open-loop control device of the internal combustion engine in such a way that the target speed (n_soll) can be transmitted by the closed-loop control device to the open-loop control device.
