Guanrong Chen, Trung Tat Pham, Introduction to fuzzy sets, fuzzy logic, and fuzzy control systems

CRC Press LLC, 2000. — 328 p.In the early 1970 s, fuzzy systems and fuzzy control theories added a new dimension to control systems engineering. From its beginnings as mostly heuristic and somewhat ad hoc, more recent and rigorous approaches to fuzzy control theory have helped make it an integral part of modern control theory and produced many exciting results. Yesterday's "art" of building a working fuzzy controller has turned into today's "science" of systematic design.
