Abstract
A method for setting up the memory of an electronic controller operates using fuzzy logic, whereby predetermined membership functions f(m) of logic variables M, defined within a universe of discourse 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 includes a central control unit provided with a memory section for storing predetermined values 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. This method provides for storing into the memory section only the values of those membership functions f(m) which have a value of the degree of membership other than zero at the points m of the universe of discourse.
