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).

Abstract: Method of parallel processing of multiple inference rules (R) organized in fuzzy sets or logical functions of multiple fuzzy sets comprising membership functions (I') defined in a so-called universe of discourse (U) and said inference rules (R) being configured essentially as IF-THEN rules with at least one antecedent preposition and at least one consequent implication and each preposition comprising at least one term (T) of comparison between membership functions (I') and a plurality of input data (I) and each term (T) being separated by logical operators (OL). The method comprises at least one phase of calculation of the weight ( OMEGA ) of each term (T) of the antecedent part of each fuzzy logic inference rule as the greatest value of the intersection between the set of input data (I) and the corresponding membership functions (I').
