In this paper we solve the problem of modeling the production systems basing on neuro-fuzzy models and tools of MATLAB. The problems of identifying and constructing a model for the prediction of energy consumption are observed with the use of MATLAB tools.
Transformer is a vital component of electric power systems for transmission and distribution. Robust design for the efficiency enhancement is the main stress in the fabrication of a transformer. Efficiency of a practical transformer is limited by the losses which are accounted for the design and manufacturing imperfections. This paper deals with the simulation, design and fabrication of a 0.30 KVA,...
This paper presents work that uses field-programmable gate arrays (FPGAs) to accelerate Simulink simulations of electrical machines on a desktop computer by more than 100 times. These simulations operate and can be modified transparently in the Simulink environment with no FPGA expertise required. This offers the prospect of low-cost, highperformance simulation workstations supporting large simulations...

The basic analyzing approaches are explained and the performance of busbar protection is discussed by the simulation and calculation results...
The wireless sensor networks — RSSFs are composed of a large number of distributed nodes, reduced dimensions that work together to perform a task. This type of network has been the subject of intensive research, and has applicability in several areas, such as environment monitoring, robotics and in the medical field. This paper deals with the application of wireless sensor networks in the medical...
Solar Photovoltaic (PV) power keeps changing with solar insolation(S) and ambient temperature (T) because PV cell exhibits non-linear current-voltage characteristic. So the Maximum Power Point (MPP) varies with the changing S and T. However with the advancement of power electronics converter technology, it is now possible to operate the PV power at its MPP in order to improve the overall efficiency...
This paper deals with simulation model of manipulator arm. Main objective of simulation is verification of methodology for manipulator positioning according to predefined trajectory. Methodology used in simulation is based on iteration method, which positions the endpoint of manipulator arm to reference coordinates.
This paper presents the options for determining power losses in the system consisting of indirect frequency converter and induction machine. A mathematical model for calculation of individual losses in machine as well as in converter is presented herein. The model allows the determination of losses both in steady states and in the course of transients, e.g. starting, braking, load change. The model...
With the construction of HVDC (high voltage direct current) transmission project, the operation personnel have increasingly strong demand. At the same time, due to the requirements of the reliability of the power grid, the new operators need to go through a training to perform their work well. The paper briefly investigates a realization method of UHVDC (ultra high voltage direct current) simulation...

The article introduces two novel open-source tools for model-based FPGA design and verification. The concept, functionality, key advantages and the result of implementation in FPGA design projects are described. New tools are shown not only to cover all needs of FPGA developers, but also to allow reaching a new level in FPGA design verification.
We study the software simulation of physical properties of underwater communications, namely, underwater acoustic waves and (de)modulation of underwater acoustic digital data signals. We take into account the mobility of nodes, present in underwater sensor networks. We also consider the integration with protocol layers above the physical layer, i.e., the link and network layers. In this context, mobility...
We describe a software system known as the Plasma Control System Simulation Platform (PCSSP) that is being constructed to support development of the ITER plasma control system. When mature, PCSSP will provide support for industry standard practices such as model-based controller design, simulation testing of controllers, auto-generation of controller code, hardware- and software-in-the-loop testing,...
This paper presents modelling of a 2-axle railway vehicle using two different simulation packages and compares simulation results of the two models. A simplified model of the railway vehicle is developed in ‘Matlab/Simulink’ environment and a full model is obtained by building/connecting blocks using a multi-body simulation package called ‘Simpack’. The simulation results of the two models are presented,...
This paper describes the application of two fuzzy-logic based methods of residual analysis to the winding machine. The residuals are generated using a parity space approach, based on a discrete-time linear model of the system. The designs of the two residual analysis methods, one based on fuzzy clustering, and the other on fuzzy reasoning, are described. Simulation results are presented for five sensor...
The distance of electricity transmission gets longer and longer, and capacity is also increasing, the voltage level by transport is becoming more and more high, while the stability problem of power system is more and more prominent. If the power system's stability is destroyed, that can cause blackouts, and it will form a very serious accident. This paper uses a single and infinite system as the object,...
In this paper, we share our experience in using an innovative approach of teaching Engineering Science established by the French Ministry of Education for the French national preparatory classes for grandes écoles. The engineering science curriculum has moved from theoretical-based teaching into an engineering workflow-based style that considers engineering skills as an integrated part of the learning...
Nowadays advanced software programs are actively used in the field for simulation and modeling. LabVIEW and MATLAB/Simulink are both graphical programming languages, allowing a more efficient method to perform and analyze control systems. Therefore, they are the most commonly used software programs for these purposes. Moreover; in some applications — like hardware in the loop systems, flight simulations...
For future low-priced electronics, high performance thin film transistors (TFTs) are highly desirable. One possible way towards device optimization is the downscaling of the channel length (L) which allows higher device density, smaller device configuration and better performance. In this paper, we present a simulation study of bottom gate TFTs based on ZnO as semiconductor, SiO2 as insulator layer...
