Defuzzification system for shifting and scaling centroid values |
摘要 |
In a defuzzification system having fuzzy singletons in the consequent, an inference block (1) in each rule includes a device (2) for calculating the maximum value of each fuzzy singleton, devices (3 and 4) for performing weighted and simple additions to each of the inference grades outputted from the maximum value calculating device, a device (5) (11) for dividing the weighted addition value by the simple addition value to provide a centroid value and devices (6 and 7) (12 and 13) for expanding and contracting and/or shifting the output range width of the quotient from the dividing device. Even if the input range width of the subsequent circuits and devices varies, the output range width of the centroid value can be scaled by a scaling device and also shifted by a level shifting device. The same arrangement can change and regulate the scaling or controlled variable of the consequent depending on the purpose of control.
