Abstract

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.
