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, CLOSED-LOOP CONTROL ARRANGEMENT HAVING SUCH A CLOSED-LOOP CONTROL DEVICE, POWER ASSEMBLY AND METHOD FOR CLOSED-LOOP CONTROL OF A POWER ASSEMBLY

A closed-loop control device includes: the closed-loop control device which is configured for: detecting a generator frequency (f) of the generator as a controlled variable; determining a control deviation (e) as a difference between the generator frequency (f) which is detected and a target generator frequency (f); determining a target torque (M) as a manipulated variable for controlling an internal combustion engine as a function of the control deviation (e); using a control rule for determining the target torque (M); and adapting the control rule—which is used to determine the target torque (M)—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 (f) which is detected, a target torque variable, and a generator power.
