Abstract: For the improved autonomous control of a process (2) using an apparatus (1) via setting of at least one action parameter (3) controlling the process (2), it is provided that via a measuring instrument (17), preferably a spectrometer (18) integrated into the apparatus (1), a process response (4), which the process (2) transfers in reaction to an adjustment of the at least one action parameter (3) to its immediate environment, is measured and evaluated in a computer-implemented manner, preferably using an artificial intelligence, and that based on this evaluation, the at least one action parameter (3) is automatically readjusted. This approach is applicable to biological, chemical and physical processes.
