Step Five: Defuzzify the Outputs
In order to control the HeatKnob, we need to obtain a crisp dial setting. So far, we have several of the
IF–THEN rules of the fuzzy rule base firing at once, because the inputs have been fuzzified. How do we
arrive at a single crisp output number ? There are actually several different strategies for this; we will consider
two of the most common, the center of area (COA) or centroid method, and the fuzzy Or method. The easiest
way to understand the process is with an example.
