Functionally complete element for fuzzy control hardware implementation

It is proposed to implement fuzzy control devices as multi-valued logic functions, using directly analog input variables and forming analog values of output variables. CMOS summing amplifiers are used as basic elements for designing appropriate circuits. It has been proved that a summing amplifier is a functionally complete element in arbitrary-valued logic. In a plenty of cases, this approach enables principally simplification of fuzzy logic controllers for a broad class of applications. Some fuzzy control hardware implementations using this design approach are given.
