REASONING ABNORMALITY DETECTING SYSTEM FOR FUZZY REASONING ARITHMETIC UNIT

摘要

PURPOSE:To display the generation of the reasoning abnormality by detecting and treating the reasoning abnormality due to an error of a control rule for fuzzy reasoning operation or the incomplete designing during an arithmetic operation. CONSTITUTION:A fuzzy reasoning arithmetic unit 3 performs a fuzzy reasoning operation by means of the input values given from a measured value input device 1 and a process state input device 2 and fetching plural control rules of a control rule storage device 5 via a control rule input device 4. Thus the output value obtained from a membership function for output is delivered from a control output device 6 in the form of the control output and also displayed on a control state display command device 7 and a control state display device 8. Then a reasoning abnormality detection parameter input device 9, a reasoning abnormality detector 10, a reasoning abnormality state display device 13 and a reasoning abnormality state display command device 12 are added to a fuzzy control device. Thus an output membership function given from the unit 3 is collated with the parameter given from the device 9 for study. Then the abnormality of the reasoning operation is detected and displayed.
