Abstract

Abstract A fuzzy inference system which has both a fuzzy inference processing device (the fuzzy inference unit) and a calculation processing device. The linguistic values in the antecedent or consequent described in the inference rule, the real numerical values in the consequent, and the values of the variables set in the calculating and computing schemes are essential to processing and are generally contained in the fuzzy inference knowledge. If these values are not present in the fuzzy inference knowledge stored in the fuzzy inference device, that device transmits to the calculation processing device the information needed to calculate them. The calculation processing device executes the calculation processing. It then sends the results of the calculations back to the fuzzy inference device, which will then continue performing the fuzzy inference.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 47 words
A fuzzy logic system comprising: a fuzzy inference unit for performing fuzzy inferences, and a CPU for calculating fuzzy inference data and outputting results of said calculations to raid fuzzy inference unit, said fuzzy inference unit performing a fuzzy inference using said results output by said CPU.
Claim 2
Dependent Claim 35 words
A fuzzy logic system as in claim 1, wherein said fuzzy inference unit comprises: a fuzzy inference engine, and an inference memory for storing data on which said fuzzy inference engine performs a fuzzy inference.
Claim 3
Dependent Claim 25 words
A fuzzy logic system as in claim 2, wherein said inference memory stores inference rules, linguistic values used in said inference rules, and membership functions.
Claim 4
Dependent Claim 33 words
A fuzzy logic system as in claim 3, wherein said CPU performs said calculations when said fuzzy inference engine does not contain data in said inference memory necessary for performing said fuzzy inference.
Claim 5
Dependent Claim 67 words
A fuzzy logic system, comprising: a fuzzy inference unit for performing fuzzy inferences according to data stored in said fuzzy inference unit; requesting means for requesting additional data when said stored data is not sufficient for said fuzzy inference unit; and a CPU, receiving a request for data from said requesting means, for calculating said additional data and outputting said additional data to said fuzzy inference unit.
Claim 6
Dependent Claim 16 words
A fuzzy logic system as in claim 5, wherein said requesting means requests a linguistic value.
Claim 7
Dependent Claim 16 words
A fuzzy logic system as in claim 5, wherein said requesting means requests a membership function.
Claim 8
Dependent Claim 16 words
A fuzzy logic system as in claim 5, wherein said requesting means requests a circulation scheme.
Claim 9
Dependent Claim 16 words
A fuzzy logic system as in claim 5, wherein said requesting means requests a defuzzyfying scheme.
