Fuzzy inference system having a dominant rule detection unit

摘要

A fuzzy inference system includes a rule processing means for receiving an input signal and inferencing the input signal in accordance with a plurality of fuzzy rules to generate inferenced data (B1, B2, B3, A1, A2, A3), a defuzzify means (19, 20, 119, 120, M1, 201, 203) for synthesizing and defuzzifying the inferenced data to generate a decided value (eO), and a dominant rule means (21, 121, 210) receiving the inferenced data and decided value for finding a dominant rule of the plurality of fuzzy rules which has the largest contribution degree to the decided value.
