| Fig 4— If two triggered rules specify output actions of "Drive_Current is Med_Large" (m=0.35) and "Drive_Current is Large" (m=0.75), the centroid method of defuzzification lops the tops off the respective membership functions at the specified m and then finds the center of mass of the centers of mass of the resulting areas. This is the same as treating the indicated regions as two metal plates, glued together and locating the balance point. In this example, the defuzzified output, which will execute, is approximately Id=1.23A (heavy vertical arrow). |
