Abstract

A method for operating an closed-loop control system for injecting fuel into an internal combustion engine, with the control system having an error correcting capability for deviations that occur in the control signal being processed by the control system, and with the control system having a controlling element, which is embodied as a precontrol, PI-controller that are operated in parallel, and a non-volatile memory for storing deviation signals.
