An output controller for an engine control for an engine system having an internal combustion engine and an electric generator coupled to the internal combustion engine. The output controller including a computing device, an inertia compensator, and an efficiency calculator. The computing device is configured to calculate a target rotational speed for the electric generator and an output torque for the internal combustion engine The inertia compensating device is configured to calculate a torque transmitted to a shaft of the generator and a desired torque for the internal combustion engine. The efficiency calculator is configured to calculate a degree of efficiency of the engine system and to adapt the value for a mechanical target output for the engine system.

The invention relates to a phase control loop for the rotational speed regulation of an electric generator fed by an internal combustion engine, having an input connection, which is designed to receive a rotational speed signal measured on a drive shaft of the electric generator, an amplitude determination device, which is coupled to the input connection and which is designed to determine the amplitude of rotational speed ripples of the measured rotational speed signal, a correction function device, which is coupled to the amplitude determination device and the input connection and which is designed to determine a rotational speed correction signal on the basis of the determined amplitude of the rotational speed ripple and of the measure rotational speed signal, a phase discriminator, which is coupled to the amplitude determination device and the correction function device and which is designed to determine a phase difference signal between the measured rotational speed signal and the rotational speed correction signal, wherein the correction function device is designed to regulate the rotational speed correction signal on the basis of the determined phase difference signal to a phase difference of zero, and a summing element, which is designed to subtract the rotational speed correction signal from the measured rotational speed signal and to provide a corrected rotational speed signal to an output connection of the phase control loop.
