摘要
A fuzzy rule acquisition method for a fuzzy inference system in which a fuzzy inference is achieved based on fuzzy knowledge including fuzzy rules each described in a format having an IF part and a THEN part, and membership functions defining meanings of respective propositions described in the IF part and THEN part, and in which a fuzzy inference is performed for at least one input value by using the fuzzy rules of the fuzzy knowledge to obtain a result of the execution of the fuzzy inference (Step 101), the result of the execution of the fuzzy inference is compared with a teaching value to obtain an inference error (Step 102), the errors of the fuzzy rules are obtained by using the inference error (Step 103), it is judged whether each of the fuzzy rules is contradictory, based on the errors of corresponding rules of the fuzzy rules (Step 105), and a fuzzy rule judged as contradictory is modified to dissolve the contradiction (Step 106).
