Abstract: 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. The controller is of a kind which includes 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 to the output of the central unit to convert the results of the inference operations back to analog or digital signals.
