Hardware Realization of Interval Type 2 Fuzzy Logic Controller

Abstract

Form the publication of Prof. Loftis’ fuzzy set theory and linguistic approach, fuzzy logic has become one of the major research topic for researchers. The type 1 fuzzy logic controller has already been used in many areas such as consumer electronics, defense, aerospace engineering etc. This type 1 fuzzy system does not model the fuzziness of the membership function or in other terms it does not deal with uncertainty very well. The control problems where more accuracy is needed, type 1 fuzzy system unable to satisfy their requirements. If a type 2 fuzzy controller is designed, it will have great application in control industry. Type 2 fuzzy system can deal with fuzziness in the decisions or in the membership functions. Membership functions are the decisions of an expert. This inclusion of uncertainty in the design will give us much better control behavior. The design and hardware realization of interval type 2 fuzzy logic controller is aim of this work. The way of design or methods of design much more important as it will give a clear understanding to the reader.
