Fuzzy rule generator

Abstract

Abstract A fuzzy rule generator for generating fuzzy rules, comprising: a selection unit for selecting two or more sets of rules from a plurality of basic sets of rules which may be stored in memory; and a control unit for generating a new set of rules by carrying out a synthetic arithmetic operation based on a predetermined set of rules for synthesis. This process of synthesis may simply consist of addition or subtraction. Thereby, a new set of rules can be easily generated by carrying out a simple arithmetic operation for each application. Therefore, generation and modification of rules are simplified and speeded up, with additional benefits arising from an efficient utilization of existing sets of rules. Further, by imposing a constraint on the newly synthesized set of rules manually, automatically or by a combination of both according to a predefined algorithm, it is possible not only to ensure the stability of the system but also to obtain desired control characteristics. If desired, the newly created sets of rules may be added to the library of the basic sets of fuzzy rules.
