The formal system L of fuzzy propositional logic has been successfully applied to the joint research of fuzzy logic and fuzzy reasoning. The current paper further studies the syntactic structure of the system L, presents several new results with respect to this system. Especially, a simplified system which contains only seven axioms is proposed, and the system is found to be equivalent to the o...

This work shows a stand-alone photovoltaic system application based on fuzzy logic controllers and genetic fuzzy systems. A hierarchical fuzzy controller has been designed that at present controls four real stand-alone photovoltaic systems sited in University of Jaén. In order to improve that fuzzy logic controller operation, a genetic fuzzy system has been designed. Its operation is based on a...

The microturbine generation (MTG) system are becoming the popular source of distributed generation (DG) due to their fuel flexibility, reliability and power quality. The MTG system is a complicated thermodynamic electromechanical system with high speed of rotation, frequency conversion and its control strategy. In spite of several techniques to control high speed of microturbine is not accurate...

This paper addresses some of the potential benefits of using f u z z y logic controllers to control an i n v e r t e d pendulum system. The stages of the development of a fuzzy logic controller using a four input T a k a g i -Sugeno fuzzy model were presented. The main idea of this paper is to implement and optimize fuzzy logic control algorithms in order t o balance the inverted pendulum and a...

The paper presents a model that demonstrates the usage of fuzzy logic on an embedded microcontroller. Fuzzy logic is a new and innovative technology being used to enhance control engineering solutions. It allows complex system design directly from system’s control human experience, thus quickly rendering efficient solutions. This paper discusses the design of car's fuzzy control system, as well...

Prompt detection and diagnosis of faults in industrial systems areessential to minimize the production losses, increase the safety of the operatorand the equipment. Several techniques are available in the literature to achievethese objectives. This paper presents fuzzy based control and fault detection for a6/4 switched reluctance motor. The fuzzy logic control performs like a classicalproporti...

for a long time, the concept of sustainability and unsustainability, the ways to assess them, and the factors involved in the process of various areas of scienc, especially the environmental ones. sustainability in rural areas as human settlements depends heavily on a series of factors including environmental and socio-economic factors. this paper aims at introducing fuzzy set theory and the ex...

An evolutionary fuzzy controller that drives the output parameters of fuzzy logic system in such a way that the Lyapunov function and the system is exponentially stable is presented. The output parameters of the fuzzy logic system are updated for every sampling time in an evolutionary manner. Only part of the parameters associated with the current situation are considered and, thus, the present...

Common uses of fuzzy logic control today are found in relatively simple applications in products. These applications only scratch the surface of the potential of fuzzy logic control in complex mechatronic systems. In order to demonstrate the utility of fuzzy logic in complex device control, a fuzzy logic fly-by-wire system has been developed for a model airplane. The model airplane is a complex...
