This paper presents an ac-dc-ac reversible six-phase machine drive system. It is composed of single-phase bridge converters connected in series in the grid side and single-phase bridge converters connected at the machine phase terminals. The proposed topology eliminates the input isolation transformers and reduces the power processed by converter switches and the harmonic distortion in the grid side. The model and the control strategy have been developed. Simulation and experimental results are presented.

This paper presents an open-end winding permanent magnet synchronous generator system with reduced controlled switch count, which may be applied to Wind Energy Conversion Systems (WECS). The configuration is obtained from the blend of a three-phase controlled rectifier (composed only of controlled switches), a non-controlled rectifier (composed only of diodes) and an open-end winding machine. A detailed model and a PWM control strategy of the systems, including the synchronism technique are presented to ensure the elimination of zero-crossover distortion normally caused by the use of diodes. Simulation and experimental results are also presented.

This paper presents a topology based on the interconnection of single-phase H-bridge converters and a three-phase converter acting as a shunt active power filter. Contributions for the model, PWM approach and control strategies are presented to the studied converter. As compared to the conventional solution by using just H-bridges converters, the proposed one reduces the number of semiconductor and storage devices while keeping the same characteristics of high number of levels. A comprehensive THD analysis will be considered followed by simulated and experimental outcomes.

Educational robotics classes consist of the use of robots in classes that involve interdisciplinary or social themes, creating innovative learning environments involving the use of such technology. In the usually known approach, educational robotics uses robotics kits. We developed a robotic simulator, called S-Educ, which can be used as an alternative or in association with robotics kits in classes involving the use of robotics. Simulators are not replacements of robotics kits, but an alternative for cases where the kits can not be used or they are not appropriate. Tests were carried out to analyze the use of the simulator, obtaining good results on the application of this simulator in educational robotics classes.

The amount of data generated in different knowledge areas has made it necessary the use of data mining tools capable of automatically analyzing and extracting knowledge from datasets. Clustering is one of the most important tasks in data mining and can be defined as the process of partitioning objects into groups or clusters, such that objects in the same group are more similar to one another than to objects belonging to other groups. In this context, this paper aims to propose an adaptation of a bee-inspired optimization algorithm so that it is able to solve data clustering problems. The algorithm was run for different datasets and the results obtained showed high quality clusters and diversity of solutions, whilst a suitable number of clusters was automatically determined. © 2013 IEEE.

This paper investigates a three-phase shunt power filter based on three standard three-phase interconnected converters. Compared with the usual three-phase shunt filter, the proposed converter permits to reduce the dc-link voltages and reduce either harmonic distortion or switching frequency. Control strategies suitable to control the filter and circulating currents as well as the three dc-link voltages are presented. A PWM strategy is designed to command the converter according to the reference voltage generated by the controllers. Simulation and experimental results are presented.

In order to operate a public transportation system, it is necessary to plan the grounded fleet lines among the various origin/destination spread all over the city to better attend population displacement during the day, which uses the bus transportation system. To improve planning operation of the public transportation system, it is proposed a linear programming model to optimize the overall performance of transit systems, by setting the optimum buses fleet for every bus line of each company constrained to an accepted delay between any two bus stop on the bus circuit but with a minimum profit for the companies. As the routes are different for time to time during the day such as rush hour. The proposed model can cope with all the kinds of patterns during the day and the propose is to optimise the whole transportation system. It is discussed also the complexity of the nature of the dynamic of the transportation system. The mathematical modelling can show us correctly a way to qualify and quantify the routes, what helps to understand the dynamic behavior of the population through time, different situations and epochs. Simulations present the viability of implantation for real time system to estimate the transportation system as it changes.

This paper presents a shunt active power filter based on the concept of open-end winding (OEW) transformers. The proposed configuration is constituted of two converters with three legs each series connected throughout a three-phase OEW transformer. Model PWM strategy and control scheme are presented as well. The main advantage of the proposed system lies on the multi-level waveform generation, which allows reduction of either harmonic distortions or switching losses. This proposed topology is suitable for medium voltage (MV) distribution systems. Simulation and experimental results validate the theoretical study.

This article aims to present the methodologies of development, analysis and system design of an Electronic Bengal, with object-oriented and structured methods, trying to establish the main features of these. From this scenario, several methods of system analysis are available for use. Among the studies conducted to develop the system, using automation techniques, are SART (Structured Analysis Real-Time) and UML (Unified Modeling Language) modelings. Each has its peculiarities, both in the way of diagramming and about the script. The project proposes an electronic device with an embedded system that contains a control algorithm to enable vibration and audio electromechanical transducers. The project is an electronic device based on open-source flexible platforms to assist in the orientation and mobility of the visually impaired during their displacement.
