ABSTRACT:
A fuzzy inference engine has a plurality of individual inference sections and a concluder section for integrally processing outputs from the inference sections. In order to simplify the fuzzy inference engine, nonfuzzy output is obtained through a simple arithmetic operation. Each fuzzy inference section comprises at least one membership function circuit and a predetermined operation circuit. A setting element sets the center position of a membership function of a consequent of each rule. A multiplier multiplies a value from the predetermined operation circuit by the center position from the setting element. A first adder sums the resulting product for each inference first adder by the values from theb section. A second adder sums the values from the predetermined operation circuit for each inference section. A divider divides the values from the second adder to produce the nonfuzzy output. As an option, and additional multiplier multiplies the output from the predetermined operation circuit by a coefficient.
