Abstract
A control system for the supercharging pressure of a supercharged internal combustion engine includes, for the purpose of using the dynamic properties of the turbocharger with adjustable turbine geometry of the internal combustion engine with respect to the supercharging pressure buildup, an open-loop control device in the operating path to the actuator; a turnoff regulating device for determining a regulation pulse duty factor which can be fed additively to the operating path; a changeover device arranged between the regulating device and the operating path; and a precontrol device for calculating a graduated precontrol pulse duty factor which can be fed to the operating path via an adder.
