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.
