A control system which operates on fuzzy logic is known as a fuzzy
system or a fuzzy control system. Fuzzy logic is a mathematical system
which does not operate on absolute binary values of 0 or 1, but instead
analyzes analog input values in terms of logical variables that take on
continuous values between 0 and 1. Fuzzy systems have found a variety of
uses in different fields, from vacuum cleaners to autofocusing cameras
and air conditioners. The design of the fuzzy control system is based on
empirical methods, which is basically a methodical approach to trial and
error. Fuzzy control systems is an upcoming field of science that has
undergone rapid development over the past few decades. The extensive
content of this book provides the readers with a thorough understanding
of the subject.
