Fuzzy inference system having a dominant rule detection unit
Patent 5179625 Issued on January 12, 1993. Estimated Expiration Date: May 5, 2012. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
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.
