A fuzzy logic electronic controller whereby predetermined membership functions mu (x) of logic (X) variables are subjected to so-called inference operations configured essentially as IF-THEN rules with at least one front preposition and at least one rear implication, and being of a kind which comprises an input or fuzzyfier section having a plurality of inputs for analog or digital signals, a central control unit or fuzzy controller core placed after said input section and being provided with memories, and an output section or defuzzyfier connected after the central unit to convert the results of the inference operations back to analog or digital signals, comprises: a plurality of fuzzyfiers (10) being disposed in parallel within said input section (3) and each led to a pair of analog and digital inputs (IiA,IiD), a plurality of storage modules (7) corresponding in number to said fuzzyfiers (10) and containing data of the front (IF) prepositions only of said rules, a fuzzy controller inference unit (11) active in the central control unit (5) to carry out logic operations based on said inference rules of the fuzzy logic by extracting data from said memories (7) through an interfacing circuit (9), and an additional memory (13) connected between the fuzzy controller inference unit (11) and the defuzzyfier (15) and adapted to contain data pertaining to the rear (THEN) implications only of said inference rules. <IMAGE> |
