    Abstract: PURPOSE: To provide a fuzzy logic electronic controller depending on so called inferring operation in which the prescribed membership function of a logical variable is substantially constituted as a preposition being at least one front part and the rule of 'If...then...', with implication being at least one rear part. CONSTITUTION: This fuzzy logical electronic controller is the kind of including an input part namely a fuzzy fire part 3 provided with plural inputs for an analog signal and digital signal, a central control unit namely a fuzzy controller central part 5 provided behind the input part and provided with plural memories, and an output part namely defuzzy fire 15 connected to the output side of the central control unit and converting the result of inferring operation back to an analog or digital signal.

    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, 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.

    Abstract: An architecture for an electronic controller operated using fuzzy logic, including an input section (3) with a plurality of inputs for analog or digital signals, a central control unit (5) provided with memories (7) wherein fuzzy logic membership functions are stored, and a defuzzyfier section (15), has its input section (3) composed of a plurality of fuzzyfiers (10) arranged in parallel and independent of one another, each fuzzyfier including an analog input (IiA) and a digital input (IiD) for receving signals from external sensors, and digital outputs connected to the input of a corresponding read-only memory (7) of the central unit to select the address of a memory word.
