Abstract

A method for controlling at least one actuator in a mass flow duct, which makes it possible to implement a predefined pressure upstream from the at least one actuator more rapidly. The flow resistance of the mass flow duct is modified by controlling the at least one actuator. A pressure upstream from the at least one actuator in the mass flow duct is predefined. A variable characterizing the flow resistance of the mass flow duct is determined as a function of the predefined pressure. The at least one actuator is controlled to set the related variable characterizing the flow resistance of the mass flow duct.
