An introductory book that provides theoretical, practical,
and application coverage of the emerging field of type-2 fuzzy
logic control
Until recently, little was known about type-2 fuzzy controllers
due to the lack of basic calculation methods available for type-2
fuzzy sets and logic--and many different aspects of type-2
fuzzy control still needed to be investigated in order to advance
this new and powerful technology. This self-contained reference
covers everything readers need to know about the growing field.
Written with an educational focus in mind, Introduction to
Type-2 Fuzzy Logic Control: Theory and Applications uses a
coherent structure and uniform mathematical notations to link
chapters that are closely related, reflecting the book's
central themes: analysis and design of type-2 fuzzy control
systems. The book includes worked examples, experiment and
simulation results, and comprehensive reference materials. The book
also offers downloadable computer programs from an associated
website.
Presented by world-class leaders in type-2 fuzzy logic control,
Introduction to Type-2 Fuzzy Logic Control:
Is useful for any technical person interested in learning
type-2 fuzzy control theory and its applications
Offers experiment and simulation results via downloadable
computer programs
Features type-2 fuzzy logic background chapters to make the
book self-contained
Provides an extensive literature survey on both fuzzy logic and
related type-2 fuzzy control
Introduction to Type-2 Fuzzy Logic Control is an
easy-to-read reference book suitable for engineers, researchers,
and graduate students who want to gain deep insight into type-2
fuzzy logic control.
