Date May 16, 1991.A process and a device for automatic determination of parameters for process control systems with unknown transfer behavior are useful for controlling special technical processes in which a functional relationship between process input and process output variables is unknown, at least in parts, while maintaining the properties of the output variables (target functions) within certain acceptable limits. To this end, measured values obtained by the process are subjected to statistical analysis from which control parameters such as theoretical value functions and weighting factors are derived automatically and incorporated in a universally applicable control specification. The control specification is used to determine the control parameter. Adaptation to different processes as well as suitability tests for various control parameters for process control can be carried out comparatively simply using predetermined calculation procedures, conversion factors or the like.
