Abstract
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.
Claims10
A fuzzy inference system, comprising:
- (a) rule processing means for receiving an input signal and for generating first data in accordance with a plurality of fuzzy rules, said rule processing means comprising:
- at least one rule processor for applying said fuzzy rules and for generating a plurality of second data;
- (b) defuzzifying means for receiving said first data and for generating a decided value;
- (c) dominant rule number means for receiving said plurality of second data and said decided value and for finding a dominant rule of said plurality of fuzzy rules which has the largest contribution to said decided value;
- and
- an actuator for receiving said decided value from said defuzzifying means and for controlling an external object in accordance with said decided value.
