PCT No. PCT/DE95/00946 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Jul. 18, 1995 PCT Pub. No. WO96/04601 PCT Pub. Date Feb. 15, 1996A defuzzification device in which, depending on selection signals (FA1, FA2) and aggregated regulation weights ( gamma ), either in a maximum process a first/last maximum value at which an associated aggregated regulation weight is a maximum is selected as the sharp output value (g) and an activation signal (ENGARZ) is formed or, as an alternative, in a first or second center of gravity process (COG12) a sharp output value (g) is formed from center of gravity coordinates (S nu ) and aggregated regulation weights ( gamma nu ), alone or additionally using area measurement figures (F nu ), adders (ADD1, ADD2) with a register (Z-Reg, N-Reg) connected downstream in each case, a multiplier (MULT) and a divider (DIV) being able to be used advantageously both for the first and for the second center of gravity process, and one of the adders (ADD2) being used for the formation of the activation signal (ENGARZ), if a defuzzification is being carried out according to the maximum process.
