Claim One:
1. A control system for controlling an infusion apparatus, comprising: a semantic analyzer, a measurement value processing unit for generating a plurality of input values for the semantic analyzer from at least one of a plurality of measurement values and a plurality of linguistic variables, the semantic analyzer comprising a first fuzzy control unit for combining the plurality of input values into semantic domains and for assigning each of the input values to a condition scale having a plurality of individual conditions, each of the domains being analyzed through stored fuzzy sets and the condition scale by detecting a membership grade for each of the individual conditions of the condition scale, an evaluation unit for weighting the membership grades according to their domain and for generating a semantic evaluation value for each domain, a second fuzzy control unit for each domain for generating a domain-specific control value based upon the membership grade of the respective domain and the semantic evaluation value, and a control value accumulator for combining the specific control values for a plurality of domains into a total control value for the infusion apparatus.
