Fuzzy logic controller (FLC) is given in this chapter. Rule development, the way of putting experts' ideas into rules and inference system structure are studied. From crisp input variables to crisp output, all processes are discussed and shown. Defuzzification, rule processing, fuzzy reasoning and crisp output after defuzzification are explained. User-developed FLC examples are given.
