Claims
- 1. A rule verifying apparatus for fuzzy control, comprising:
- a memory device storing set fuzzy rules and fuzzy membership functions concerning input and output variables and related to the set rules;
- an input device for specifying at least one stored fuzzy rule to be temporarily excluded from said set rules when the set rules are used in a fuzzy inference operation; said at least one temporarily excluded rule remaining stored along with the other set rules;
- a fuzzy inference device connected to said memory device and said input device and which subjects an input value to a fuzzy inference operation using said stored set rules excluding said at least one stored rule specified as being temporarily excluded, to obtain a corresponding output value; and
- an output device connected to said fuzzy inference device which outputs the output value obtained by the fuzzy inference operation performed by said fuzzy inference device.
- 2. The rule verifying apparatus for fuzzy control according to claim 1, wherein said specifying device specifies a plurality of stored rules to be temporarily excluded.
- 3. The rule verifying apparatus as in claim 1, wherein said outputting means is a display device for displaying said output value.
- 4. A rule verifying method for fuzzy control comprising the steps of:
- storing in a storage device set fuzzy rules and fuzzy membership functions concerning input and output variables and related to said set rules;
- specifying with an input device at least one stored rule to be temporarily excluded from said set rules when the set rules are used in a fuzzy inference operation, said at least one temporarily excluded rule remaining stored along with the other set rules;
- subjecting an input value to a fuzzy inference operation with a fuzzy inference processor using said stored set rules excluding said at least one rule specified as being temporarily excluded, to obtain a corresponding output value; and
- outputting said output value obtained by said fuzzy inference operation to an output device.
- 5. The method for verifying rules for fuzzy control according to claim 4, wherein said specifying step specifies a plurality of stored rules to be temporarily excluded from said set rules.
- 6. The method for verifying rules for fuzzy control according to claim 4, wherein said outputting step displays said output value on a display device.
