Abstract
This paper proposes an eclectic approach for the efficient computation of fuzzy rules based on fuzzy logic and signal processing techniques. The rules {R r} of the MISO zero-order Takagi-Sugeno fuzzy system considered, are given in the form of R r: If X I is A rl and ... and X N is A rN then z is c r, where Xj are fuzzified input variables, A rj are standard fuzzy sets which belong to the corresponding partition of unity {A rj} and c r is a nonfuzzy singleton term of output variable z. A relevant feature of this approach is a quantitative, signal processing based, transformation of uncertainty (imprecision) of each input X j into an additional uncertainty (vagueness) on the corresponding fuzzy partition {A rj}. This transformation greatly simplifies the involved matching computation. Moreover, this fuzzification transformation gives a new set of linguistic terms {A rj’} which is also a partition the unity.
