The invention relates to a closed-loop control device (3) for closed-loop control of a power assembly (1) comprising an internal combustion engine (5) and a generator (9) having an operative drive connection to the internal combustion engine (5), in which device: - the closed-loop control device (3) has a power controller (14) which is designed - to detect a generator power (PG) as a control variable, - to determine a power control deviation (eP), and - to identify a first specification variable (16) in accordance with the power control deviation (eP), - said closed-loop control device (3) also having a frequency controller (18) which is designed: - to detect a generator frequency ((fG as a control variable, - to determine a frequency control deviation (ef), and - to identify a second specification variable (20) in accordance with the frequency control deviation (ef), - said closed-loop control device (3) also having a preselection module (22) which is designed to identify a third specification variable (24), - said closed-loop control device (3) being designed to combine the first specification variable (16), the second specification variable (20) and the third specification variable (24) with one another to form a total specification variable (26), and - to use the total specification variable (26) for controlling the internal combustion engine (5).
