Abstract

A method for operating a boost pressure control in an engine system having a supercharged internal combustion engine, including the following: performing a boost pressure control based on a setpoint controller variable and an actual controller variable, ascertaining a setpoint controller variable from a provided setpoint boost pressure with a first and a second model, ascertaining an intermediate variable from a provided actual boost pressure with the first model, correcting the intermediate variable with a provided dynamic variable, which represents a dynamic change in the state of the engine system using a higher dynamics than the actual boost pressure, and ascertaining the actual controller variable from the corrected intermediate variable with the second model.
