Introduction to fuzzy systems

Fuzzy logic was first developed by Zadeh in the mid 1960s for representing uncertain and imprecise knowledge. In the classical Boolean logic truth is represented by the 1 state and falsity is by the 0 state. Boolean algebra has no provision for approximate reasoning. Fuzzy logic is an extension of Boolean logic in the sense that it also provides a platform for handling uncertain and imprecise knowledge. Fuzzy logic uses fuzzy set theory, in which a variable is a member of one or more sets, with a specified degree of membership, usually denoted by the Greek letter μ. The paper provides an introduction to fuzzy systems
