Abstract

By providing a detailed hierarchical structure for an APC algorithm and by dynamically adapting a hierarchical level in this structure, an efficient utilization of controller data is ensured, while at the same time a large number of process conditions may be taken into consideration without requiring a re-design of the hierarchical structure.
