Abstract: A controller for an injection system having a plurality of fuel injectors includes a map controller. From a desired injection value, the map controller generates a control value for actuating a fuel injector with reference to a specified map.

From this input, the adaption unit generates adapted actuation values as output by applying a mathematical function to the control values generated by the map controller. The at least one adaption value is included in the first mathematical function as parameter.
