detection method and classification method of process defects using fuzzy logic

摘要

That monitors big motor to detect and identify failure to fuzzy logic controller for dcs. The monitored fuzzy logic controller of variable includes that oil pressure, oil temperature and other key variables are using trip off line under a classical logic to motor. Input and output membership function in such a way, identification and rule set define the variable of fuzzy logic controller blurring monitoring to the input membership function, determine leading true value, be related to antecedent true value to the output membership function, establish fuzzy output collection. It is combined in multiple output fuzzy sets, they merge. It exports fuzzy set or merges combined output fuzzy set and be converted to crisp value.
