Abstract
A device for controlling the exhaust-gas turbocharging of an internal combustion engine having an exhaust-gas turbocharging device, has an estimated value unit for determining a mass flow through a turbine system, a regulating unit for determining a regulating exhaust-gas back pressure as a function of a nominal charge pressure and an actual charge pressure, and also a unit for generating at least one actuating signal for at least one actuator of the turbine system as a function of the regulating exhaust-gas back pressure and of the mass flow through the turbine system, wherein the estimated value unit has a turbine system model for determining an estimated overall efficiency of the turbine system and a model for determining an estimated overall efficiency of a compressor system having at least two compressors, and wherein the regulating unit is set up to determine the regulating exhaust-gas back pressure using the estimated overall efficiencies
