Abstract (en)

[origin: WO9530186A1] A fuzzy processor comprises a fuzzifier which calculates the appurtenance values of the relevant input-appurtenance functions from the digital input signal. To this end, the appurtenance functions must be stored. In order to reduce the storage space needed, especially at a high input signal resolution, it is of advantage to describe the appurtenance functions by shape-determined characteristics like restart points and slopes and store these. To save computing time, the definition range of the input signal is devided into equal segments. In the fuzzifiying process only the segment is considered in which the input signal to be fuzzified lies. This thus reduces the number of appurtenance functions to be considered, which reduces computing time. The result of the process is a fuzzification of the input signals using the minimum computing time without the need for excessively large storage space of the appurtenance functions.
