wHat is fuZzy LoGic??

Fuzzy logic is a form of multi-valued logic derived from fuzzy set theory to deal with reasoning that is approximate rather than precise. In contrast with "crisp logic", where binary sets have binary logic, the fuzzy logic variables may have a membership value of not only 0 or 1 – that is, the degree of truth of a statement can range between 0 and 1 and is not constrained to the two truth values of classic propositional logic. Furthermore, when linguistic variables are used, these degrees may be managed by specific functions.

Fuzzy logic emerged as a consequence of the 1965 proposal of fuzzy set theory by Lotfi Zadeh.Though fuzzy logic has been applied to many fields, from control theory to artificial intelligence, it still remains controversial among most statisticians, who prefer Bayesian logic, and some control engineers, who prefer traditional two-valued logic.

“Sensitivity Study for Fault Detection System using Fuzzy Logic Methodology”. This study are focus on determine the best functional parameters in Fuzzy Inference System for fault detection application. In these studies, ten process faults have been designed for the experimental work and the data collected from the experiment were acted as an input into the fuzzy logic modeling. The variables of temperature, conductivity, conversion and concentration were acted as an input whereas, the process condition acted as an output for the modeling system. The sensitive studies are focusing on determine the best combination of functional parameters to detect and isolate various process condition considered in the study. - AZIM NAZRI
