A fuzzy logic system for processing type-2 fuzzy logic sets comprises a fuzzification module for receiving an input, a rules module for storing rules to be applied to the input to generate fuzzified data, a processing stage for processing the output from the fuzzification module to generate processed data: and a defuzzification module for generating a crisp output value from the processed data. The rules module has fuzzy sets, each fuzzy set having an associated first multi-dimensional geometric object which has a surface formed of one or more connected planar polygons. The processing stage generates, from the fuzzified data, a model of a further multi-dimensional geometric object comprised of a number of planar surfaces having one or more connected planar polygons. The further multi-dimensional geometric object has a geometric centre; and the defuzzification module is arranged to determine the geometric centre of the further multi-dimensional geometric object. The crisp output value comprises the geometric centre of the further multi-dimensional geometric object. This type of logic system could be used in devices such as washing machines, camcorders, lifts and in chemical plants and expert systems. |
