Fuzzy Logic Control System and its Application Area in Daily Life

The concept of Fuzzy logic and Fuzzy set are based on the human thinking and natural activities. It presents predicates which are already present in nature. This works describe the working of Fuzzy logic control system in a technical environment. Generally a fuzzy set is a superset of Boolean logic that has been extended to handle the concept of partial truth: Truth values lies between “completely true” and “completely false”. Fuzzy system can be easily implemented in Technical (hardware, software or both). It can be built anything any small handy utility system. Fuzzy logic in the narrow sense is symbolic logic with a comparative notion of truth developed fully in the spirit of classical logic (syntax, semantic, axiomatization, truth preserving deduction, completeness etc. both propositional and predicate logic. Fuzzy sets are set whose elements have degree of membership. Fuzzy sets theory permits the gradual assessment of the membership of element in set.
