Abstract: PURPOSE: To perform an operation at a high calculation speed and at the high degree of a resolution while making a required storage capacity for a hardware to carry out a belonging relation function extremely small. CONSTITUTION: This electronic controller 1A is provided with a buffer part 8 for reproducing the effective value of the belonging relation function and extracting prescribed weight included in the inference rule of fuzzy logic calculation between a storage part 5A for storing a plurality of values of the belonging relation function and the calculation part 6. The storage part 5A is a size corresponding to a large number of non-zero values of the belonging relation function related to a selected point among the finite number of points and the selected point is provided with the maximum number of the non-zero value.

Abstract: A method for setting up the memory of an electronic controller operates in Fuzzy logic, whereby predetermined membership functions (f(m)) of logic variables (M), defined within a universe of discourse (U) sampled in a finite number of points (m), are subjected to inference operations basically configured by IF/THEN rules with at least one front preposition and at least one rear implication. The controller further comprises a central control unit (3) provided with a memory section (5) for storing predetermined values (l) of the membership functions (f(m)) which appear in the front or IF part of the Fuzzy rules and have a predetermined degree of truth or membership (G). This method provides for storing into said memory section (5) the only values (l) of those membership functions (f(m)) which have a value (l) of the degree of membership (G) other than zero at the points (m) of the universe of discourse (U).
