Abstract
Fuzzy systems normally assume a predetermined and invariable membership function for the individual linguistic variables, the form and value range of the membership function being prescribed. According to the invention, individual elements in the fuzzy system such as membership functions, rules, rule weightings and the like can be changed by the automation system itself. Preferably at least one membership function is changed on-line during the operation of the automation system. In the associated arrangement with at least one fuzzy system with inputs and outputs, the software module (1, 2) responsible for fuzzyfication receives at least one additional input (30, 40-50). The proposed method and associated arrangement can be used advantageously to optimize energy consumption in factories or to control water circulation systems.
