Abstract

A method for controlling an injection system of an internal combustion engine having at least one injector, the fuel metering being divided into a first partial injection and at least one second partial injection, and a control signal which determines the fuel quantity to be injected with the aid of the at least one injector being corrected as a function of a pressure wave influencing the at least two partial injections, the pressure wave correction being performed on the basis of a periodic model which models the quantity wave as a sum of periodic functions.
