DEVICE FOR DISCRIMINATING VALIDITY IN FUZZY INFERENCE

摘要

PURPOSE:To widely detect various causes or inference abnormality based upon respective parts of constituting by comparing an object value of validity discrimination with the upper and lower limit values of a forecasting value and discriminating the validity of a value to be discriminated at its validity from the compared result. CONSTITUTION:A value to be discriminated at its validity is applied to respective comparators 13, 14 in a validity discriminating device 12 and compared with the upper limit value MAX and lower limit value MIN of its predicted value by respective comparators 13, 14. When the objective value exceeds a range between the upper and lower limit values MAX, MIN of the predicted value as the result of comparison, either one of the comparators 13, 14 outputs '1' and an OR circuit 15 forms an error output E indicating the existence of inference abnormality, so that the generation of abnormality based upon any cause in any part of the constitution can be detected. Consequently, inference abnormality based upon various factors or respective parts of the constitution can be widely detected.
