ABSTRACT:
A method for loading the memory of an electronic controller operating using fuzzy logic, whereby predetermined membership functions of logic variables, defined within a universe of discourse sampled in a finite number of points, are subjected to inference operations basically configured as 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 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 the memory section the only values of those membership functions that have a value of the degree of membership other than zero at the points of the universe of discourse.
