4.4 Defuzzification From the control advice we have to calculate a non-fuzzy numeric value for the control variable as a numeric value.The resulting membership function is composed of the superimposition of partial areas of triangles and trapezoids the position of the center of gravity of the total area on the output signal axis is the non-fuzzy value investigated[7].We can guess a mechanical system in which the three columns for the acceleration values that weight is a function of their height.The columns are balanced on a consist in along the axis.Then we can calculate the numeric control variable to find out the non-fuzzy value ; ∑ ∑ . = . , . , , . , , . , , ≈ −0,3 (Siemens user`s manual) If we consider the this example we can realize that vehicle’s brake is executed with approx %30 . 28
