FUZZY LOGIC CONTROLLER WITH OPTIMISED STORAGE ORGANISATION

摘要

A fuzzy logic controller with which it can store into an input memory (I1MEM 14MEM ...) for each input signal (I1 ... I14), numbers (NI) for of the linguistic values ​​of the input signal (I1) and the first parts and other parts of input association functions (ZL, ZH) of the input signal (I1) with which the numbers for the linguistic values can be introduced directly and via incrementing systems (INC1 ... INC4) in a regulating decoder (RDEC) by a digit multiplexer (MUX1a MUX4a ...), the control decoder providing addresses for an output memory (OMEM) downstream, and with which an output of memory output signal (OMEM) can be introduced directly into a minimum-maximum circuit (MINMAX) and the first and other portions of the matching functions input may be introduced in this circuit through matching function multiplexers (MUX1b MUX4b ...). The stage fuzzy logic object of the invention is mainly characterized by a very low occupation of memory space and, therefore, it is particularly suitable for logic controllers fuzzy integrated memory.
