CONDITIONING OF HIGH-VOLTAGE RADIO-FREQUENCY CAVITIES BY USING FUZZY-LOGIC IN CONNECTION WITH RULE-BASED PROGRAMMING

Many processes are controlled by experts using some kind of mental mod el to decide on actions and make conclusions. This model, based on heu ristic knowledge, can often be represented by rules and does not have to be particularly accurate. Such is the case for the problem of condi tioning high voltage RF cavities; the expert has to decide, by observi ng some criteria, whether to increase or to decrease the voltage and b y how much. A program has been implemented which can be applied to a c lass of similar problems. The kernel of the program is a small rule ba se, which is independent of the kind of cavity. To model a specific ca vity, we use fuzzy logic which is implemented as a separate routine ca lled by the rule base, to translate from numeric to symbolic informati on.
