ing fuzzy sets, fuzzy logic, and fuzzy inference. Fuzzy rules play a key role in representing expert control/modeling knowledge and experience and in linking the input variables of fuzzy controllers/models to output variable (or variables). Two major types of fuzzy rules exist, namely, Mamdani fuzzy rules and Takagi-Sugeno (TS, for short) fuzzy .

2.2 Fuzzy Logic Fuzzy Logic is a form of multi-valued logic derived from fuzzy set theory to deal with reasoning that is approximate rather than precise. Fuzzy logic is not a vague logic system, but a system of logic for dealing with vague concepts. As in fuzzy set theory the set membership values can range (inclusively) between 0 and 1, in

fuzzy controller that uses an adaptive neuro-fuzzy inference system. Fuzzy Inference system (FIS) is a popular computing framework and is based on the concept of fuzzy set theories, fuzzy if and then rules, and fuzzy reasoning. 1.2 LITERATURE REVIEW: Implementation of fuzzy logic technology for the development of sophisticated

A Short Fuzzy Logic Tutorial April 8, 2010 The purpose of this tutorial is to give a brief information about fuzzy logic systems. The tutorial is prepared based on the studies [2] and [1]. For further information on fuzzy logic, the reader is directed to these studies. A fuzzy logic system (FLS) can be de ned as the nonlinear mapping of an

Tutorial On Fuzzy Logic Jan Jantzen 1 Abstract Fuzzy logic is based on the theory of fuzzy sets, where an object’s membership of a set is gradual rather than just member or not a member. Fuzzy logic uses the whole interval of real numbers between zero (False) and one (True) to develop a logic as a basis for rules of inference.

Fuzzy logic versus neural networks The idea of fuzzy logic is to approxi-mate human decision-making using nat-ural-language terms instead of quantita-tive terms. Fuzzy logic is similar to neur-al networks, and one can create behav-ioral systems with both methodologies. A good example is the use of fuzzy logic for automatic control: a set of .

Fuzzy logic has two different meanings. In a narrow sense, fuzzy logic is a logical system, which is an extension of multivalued logic. However, in a wider sense fuzzy logic (FL) is almost synonymous with the theory of fuzzy sets, a theory which relates to classes of objects with unsharp boundaries in which membership is a matter of degree. In .

fuzzy logic reasoning. Once the membership functions and the rule base of the fuzzy logic controller determined, the next step is relating to the tuning process, which is sophisticated procedure since there is no general method for tuning the fuzzy logic controller [10-11]. For 3DOf helicopter simulator, fuzzy logic control was proposed in [12].

Different types of fuzzy sets [17] are defined in order to clear the vagueness of the existing problems. D.Dubois and H.Prade has defined fuzzy number as a fuzzy subset of real line [8]. In literature, many type of fuzzy numbers like triangular fuzzy number, trapezoidal fuzzy number, pentagonal fuzzy number,

A fuzzy set F in the universe of discourse U is characterized by its membership function µ F: U [0,1 ]. The fuzzy set may be represented as a set of ordered pairs of a generic element u and its grade of membership function: F {(u ,µ F (u ))/ u U }. De nition 2. A fuzzy number F in a continuous universe U, e. g., a real line, is a fuzzy set .

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. 34, Part XXX 3.2 Fuzzy inference system Fuzzy inference is the process of formulating the mapping from a given input to an output using fuzzy logic. The process of fuzzy inference involves: membership functions, fuzzy logic

Fuzzy Logic: A tutorial In a course in switching theory or traditional symbolic logic, one studies a form of logic which has existed from the early Greeks, notably Aristotle. This session reviews the principles of this crisp symbolic logic (negation, and, or, if - then, etc.) and then proceeds to introduce Fuzzy logic and Fuzzy sets.

ii. Fuzzy rule base: in the rule base, the if-then rules are fuzzy rules. iii. Fuzzy inference engine: produces a map of the fuzzy set in the space entering the fuzzy set and in the space leaving the fuzzy set, according to the rules if-then. iv. Defuzzification: making something nonfuzzy [Xia et al., 2007] (Figure 5). PROPOSED METHOD

The fuzzy logic control is designed using the fuzzy inference systems with the definition of input and output membership functions. The fuzzy sets and rules are designed and accordingly the drive can be controlled. With the usage of single antecedent fuzzy rule the intersection of fuzzy rule problem can be eliminated.

of fuzzy numbers are triangular and trapezoidal. Fuzzy numbers have a better capability of handling vagueness than the classical fuzzy set. Making use of the concept of fuzzy numbers, Chen and Hwang [9] developed fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) based on trapezoidal fuzzy numbers.

Note that a membership function of a binary fuzzy relation can be depicted with a 3D plot. (, )xy P Important: Binary fuzzy relations are fuzzy sets with two dimensional

FUZZY LOGIC FUNDAMENTALS 3.1 INTRODUCTION The past few years have witnessed a rapid growth in the number and variety of applica-tions of fuzzy logic (FL). FL techniques have been used in image-understanding applications such as detection of edges, feature extraction, classification, and clustering. Fuzzy logic poses

Fuzzy logic is an extension of Boolean logic by Lot Zadeh in 1965 based on the mathematical theory of fuzzy sets, which is a generalization of the classical set theory. By introducing the notion of degree in the veri cation of a condition, thus enabling a condition to be in a state other than true or false, fuzzy logic provides a very valuable

show the better results when fuzzy logic controller is used. Maximum overshoot for fuzzy logic controller is measured as 9.35% as compared with 47.3% given by conventional PID controller. Settling time for fuzzy logic controller and PID controller is measured at 7.18 seconds and 10.14 seconds respectively, which shows the superiority of fuzzy logic

The aim of using the Fuzzy Teaching Models is, on the one hand, the transfer of knowledge about Fuzzy Control (Mamdani Type) and the algorithms used (Lee, 1990; Driankov, Hellendoorn, & Reinfrank, M., 2013), and, on the other hand, to get to know techniques of optimization and tun-ing of Fuzzy Controllers in real technical applications.

A brief description is as follows: (1) In above formula, x i is the feature data to be clustered; m k is the center of each clus-ter; u

dynamics of each fuzzy inference (rule) by a linear system model is the main characteristics of the T-S fuzzy model. Particularly, description of the Takagi-Sugeno fuzzy systems is done by fuzzy IF-THEN rules, which linear input-output relations of a system is locally represented by. The fuzzy system is of the following form [29, 30]: Rule i IF q 1

a fuzzy subset of the input variable, which describes clearly the fuzzy partition of input space. Hidden layer 2 is used to implement the algorithm of fuzzy inference, and the number of nodes is the number of fuzzy rules, i.e., each node is associated with a fuzzy rule. The overall outputs are acquired from the output layer.

tracking control [27], large-scale fuzzy systems [28], and even fuzzy neural networks [29]. Type-1 fuzzy sets are able to effectively capture the system nonlinearities but not the uncertainties. It has been shown in the literature that type-2 fuzzy sets [30], which extend the capabil-ity of type-1 fuzzy sets, are good in representing and captur-

methods based on the fuzzy relation. These can be found in (10,12-161. Fuzzy clustering, based on fuzzy relations, was first proposed by Tamura et al. [12]. They proposed an N-step procedure by using the composition of fuzzy relations beginning with a reflexive and symmetric fuzzy relation R in X. They showed that there is an n such that

2.2 Fuzzy stabilizer The development of the fuzzy logic approach here is limited to the controller structure and design. More detailed discussions on tizzy logic controllers are widely available, e.g., [9, 12]. For the proposed FPSS. the second term of (2) is replaced with a fuzzy logic rule-base using the filtered

Accordingly, the expert systems approach has proved to be useful. As stated previously, fuzzy theory can lend itself to the representation of knowledge and the building of an expert system. In this paper we used fuzzy logic to detect the severity of fault at the output. The concept of fuzzy logic was first introduced in 1964 by
