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 (G) of truth or membership. 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),.
