fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Introduction: As we know, an implementation of fuzzy inference can be done on general purpose computer architectures (including digital signal processors and microcontrollers) or on a special fuzzy hardware [1]. Analogous and digital techniques are used. Fuzzy controllers working on stochastic logic represent a special kind of fuzzy hardware [2], [3]. The stochastic logic uses binary random sig...

Nach einer Einführung in sicherheitstechnische Begriffe wird ein Fuzzy Controller für sicherheitsrelevante Aufgaben der Prozesssteuerung vorgestellt. Es lässt sich zeigen, dass der erforderliche Umfang der Regelbasis relativ gering ist, um eine zufriedenstellende Arbeitsweise des Controllers sicherzustellen. Die Besonderheit dieses Entwurfes besteht darin, dass sich der Inhalt der Regelbasis fü...

This paper describes background and design of a model free adaptive Fuzzy Logic Controller. Controller Error Scaling Factor adaptation uses principle of balancing Error and Change of Error actions. Adaptation proceeds only if prescribed set of conditions is satisfied. Controller Scaling Factor for Change of Output adaptation uses weighted average of correction from oscillation index and process...

A concept called the decomposition of multivariable control rules is presented. Fuzzy control is the application of the compositional rule of inference and it is shown how the inference of the rule base with complex rules can be reduced to the inference of a number of rule bases with simple rules. A fuzzy logic based controller is applied to a simple magnetic suspension system. The controller h...

In many applications of motion control, the occurrence of nonlinear friction constitutes a fundamental obstacle in the design of satisfactory controlling systems. Since it is seldom possible to obtain a relatively accurate model of resistance to motion, a solution more and more often applied in practice is to introduce approaches that incorporate the inevitable imprecisions of the model in the ...

As a generalization of the triple I method, the universal triple Imethod is investigated from the viewpoints of both fuzzy reasoningand fuzzy controller. The universal triple I principle is putforward, which improves the previous triple I principle. Then,unified form of universal triple I method is established based onthe (0,1)-implication or R-implication. Moreover, the reversibilityproperty o...

In this paper several tuning methods for Sugeno's fuzzy systems wiu be discussed. &t 4he first case the fuzzy controller is identified off-line based on training data. Following this approach, first the structure of the controller is identified by means of a clustering algorithm. A Kohonen se4f-organizing neural network performs this task. TheE the parameters of the fuzzy controlier (ie. member...

compositional rule of inference to a fuzzy input X* E F ( X ) we obtain a fuzzy output Y* E F(Y): We propose an enhancement of MamY * = X * o T R , (1) dani fuzzy controllers. We tested it on l.e., a simple control task and verified that it outperforms the traditional approach. VY E Y : Y*(Y) = SUPT(X*(X),R(X,Y)) , (2) xEX

-This paper describes the realization of a fuzzy controller which implements the simplified inference mechanism. CMOS analog circuits where signals are represented as currents are employed. However, the whole system is externally communicated through voltages, thus enabling simple interface with conventional control circuitry.
