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 .

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

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,

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.

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

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

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.

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.

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-

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 .

It is the responsibility of the user to select a function that is a best representation for the fuzzy concept to be modeled. The

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 .

imprecise or vague information. Fuzzy numbers (FNs), introduced by Dubois and Prade in [10], form a particular subclass of fuzzy sets of the real line. Formally, a fuzzy set A with membership function µA: R [0,1] is a fuzzy number, if it enjoys the following properties: (i) it is a normalized fuzzy set, i.e., µA(x0) 1 for some x0 R,
