This paper reports the use of simulated annealing to design more efficient fuzzy logic systems to model problems with associated uncertainties. Simulated annealing is used within this work as a method for learning the best configurations of interval and general type-2 fuzzy logic systems to maximize their modeling ability. The combination of simulated annealing with these models is presented in...

Interval Type-2 Fuzzy Logic Controller (IT2FLC) where the fuzzy parameters, e.g. Fuzzy Membership Functions and Fuzzy Rule Bases are tuned by Genetic Algorithm (GAs) known as Genetic Interval Type-2 Fuzzy System (GIT2FS). The GFS are discussed briefly, later, the proposed design is explained. Key wordsGA, Interval Type-2 Fuzzy Logic Controller (IT2FLC), Genetic Interval Type2 Fuzzy System (GIT2...

This paper presents hardware architecture for an Interval Type-2 fuzzy processor. The architecture is based on the use of two Type-1 Fuzzy Logic Systems (T1 FLS) and it suggests that the existing techniques for implementing T1 FLS can be employed for realizing Type-2 Fuzzy Logic Systems (T2 FLS). The paper also presents a survey of the various realizations for T1 FLS and summarizes them giving ...

This paper addresses dynamics and control highly non-linear 3DOF robot manipulator o...

AND ITS APPLICATION by YU QIU Under the Direction of Yanqing Zhang ABSTRACT In recent years, the type-2 fuzzy sets theory has been used to model and minimize the effects of uncertainties in rule-base fuzzy logic system. In order to make the type-2 fuzzy logic system reasonable and reliable, a new simple and novel statistical method to decide interval-valued fuzzy membership functions and a new ...

This paper presents an implementation of a new robust control strategy based on interval type-2 fuzzy logic controller (IT2-FLC) applied to the wind energy conversion system (WECS). The generator used was variable speed turbine doubly fed induction (DFIG). Fuzzy concepts have been with great success in many applications worldwide. So far, vast majority systems type-1 controllers. However, T1-FL...

This study presents vibration control using actively tunable vibration absorbers (ATVA) to suppress vibration of a thin plate. The ATVA is made of a sandwich hollow structure embedded with electrorheological fluid (ERF). ERF is considered to be one of the most important smart fluids and it is suitable to be embedded in a smart structure due to its controllable rheological property. ERF’s appare...
