Abstract

A system for controlling the charging of an internal combustion engine contains an integral controller. If appropriate, a proportional controller and/or a differential controller may also be present. The integration, carried out by the integral controller, of the control error is limited to a prescribable limit value in order to avoid severe overshoots. Various limit values for steady-state operating states and for dynamic operating states can be prescribed. The dynamic limit value can be provided with corrections as a function of characteristic operating variables and with an adaptive correction and can be additionally increased by a safety interval.
