Abstract:
A control strategy of permanent magnet synchronous motors (PMSMs), which is different from the traditional vector control (VC) and direct torque control (DTC), is proposed. Firstly, the circular rotating magnetic field is analyzed on the simplified model and discredited into stepping magnetic field. The stepping magnetomotive force will drive the rotor to run as the stepping motor. Secondly, the stator current orientation is used to build the control model instead of rotor flux orientation. Then, the discrete current control strategy is set and adopted in positioning control. Three methods of the strategy are simulated in computer and tested on the experiment platform of PMSM. The control precision is also verified through the experiment.

Abstract:
AbstractWe introduce astepping methodologyfor answer-set programming (ASP) that allows for debugging answer-set programs and is based on the stepwise application of rules. Similar to debugging in imperative languages, where the behaviour of a program is observed during a step-by-step execution, stepping for ASP allows for observing the effects that rule applications have in the computation of an answer set. While the approach is inspired from debugging in imperative programming, it is conceptually different to stepping in other paradigms due to non-determinism and declarativity that are inherent to ASP. In particular, unlike statements in an imperative program that are executed following a strict control flow, there is no predetermined order in which to consider rules in ASP during a computation. In our approach, the user is free to decide which rule to consider active in the next step following his or her intuition. This way, one can focus on interesting parts of the debugging search space. Bugs are detected during stepping by revealing differences between the actual semantics of the program and the expectations of the user. As a solid formal basis for stepping, we develop a framework of computations for answer-set programs. For fully supporting different solver languages, we build our framework on an abstract ASP language that is sufficiently general to capture different solver languages. To this end, we make use of abstract constraints as an established abstraction for popular language constructs such as aggregates. Stepping has been implemented inSeaLion, an integrated development environment for ASP. We illustrate stepping using an example scenario and discuss the stepping plugin ofSeaLion. Moreover, we elaborate on methodological aspects and the embedding of stepping in the ASP development process.

Abstract:
The cytoskeleton plays a direct role in controlling neurite shape. To quantitatively study both the three dimensional shape and the sub-micron structure of the cytoskeleton requires complete serial reconstruction at the Electron Microscopic level. We have devised a computer reconstruction system specifically for this purpose.The system uses a 35mm film copy of 3.25 x 4.00 inch EM negative as the data source. The film is placed into a high speed film transport (15 frames/second), which is mounted on a X,Y and rotation stage controlled by stepping motors. The 35mm film is viewed through a stepping motor controlled zoom lens mounted on a high resolution (1119 x 1024) video camera. A high resolution frame grabber controlled by the computer can store one complete frame. Thus, the live image and a stored image may be displayed alternately on a high resolution monitor. Finally, a graphics overlay and mouse connected to the computer can be used to align successive sections via the stepping motors, as well as to trace the outlines of a profile, or of a microtubule.

Abstract:
Purpose The purpose of this paper is the presentation and research of a novel robot vision system, which uses laser dynamic triangulation, to determine three-dimensional (3D) coordinates of an observed object. The previously used physical operation principle of discontinuous scanning method is substituted by continuous method. Thereby applications become possible that were previously limited by this discretization. Design/methodology/approach The previously used prototype No. 2, which uses stepping motors to realize a discontinuous laser scan, was substituted by the new developed prototype No. 3, which contains servomotors, to achieve a continuous laser scan. The new prototype possesses only half the width and turns out to be significantly smaller and therefore lighter than the old one. Furthermore, no transmissions are used, which reduce the systematic error of laser positioning and increase the system reliability. Findings By using a continuous laser scan method instead of discontinuous laser scan method, dead zones in the laser scanner field can be eliminated. Thereby, also by changing the physical operation principle, the implementation of applications is allowed, which previously was limited by the fixed step size or by the object distance under observation. By using servomotors instead of stepping motors, also a significant reduced positioning time can be accomplished maintaining the relative positioning error less than 1 per cent. Originality/value The originality is based on the substitution of the physical operation principle of discontinuous by continuous laser scan. The previously used stepping motors discretized the laser scanner field and thereby produced dead zones, where 3D coordinates cannot be detected. These stepping motors were substituted by servomotors to revoke these disadvantages and provide a continuous laser scan, where dead zones in the field of view get eliminated and the step response of the laser scanner accelerated.

CAPES
A geração de energia a partir de fontes alternativas é na atualidade tema de inúmeras pesquisas e desenvolvimento no meio científico e industrial. A energia eólica destaca-se nesse cenário como uma das mais proeminentes alternativas na geração de energia elétrica, por suas inúmeras vantagens. Em trabalhos de pesquisa, a reprodução computacional e em bancada do comportamento de uma turbina eólica, incluindo simulação de grandezas mecânicas e elétricas, que afetam diretamente a conversão de energia, são ferramentas muito apropriadas para o desenvolvimento e estudo de novas tecnologias quanto ao aproveitamento do potencial eólico de uma determinada região. Este trabalho aborda estudos referentes ao processo de conversão de energia em sistemas eólicos para geração de energia elétrica, com a finalidade de se desenvolver uma ferramenta para emulação de turbina eólica em bancada experimental, utilizando software LabVIEW®. O objetivo desta ferramenta é emular o torque mecânico desenvolvido no eixo de uma turbina eólica operando em geração distribuída, a partir de uma bancada experimental constituída por motor de indução trifásico e gerador síncrono a imã permanente, sob diferentes condições de velocidade de vento. Tal ferramenta possui o objetivo de ser flexível para demais arranjos laboratoriais, ou seja, capaz de ser empregada em outras estruturas de emulação de geração eólica em tempo real. Uma modelagem do sistema eólico é apresentada, desde a turbina ao gerador elétrico, após uma ferramenta de simulação em ambiente Matlab/Simulink® é desenvolvida com finalidade de pré-validar o experimento em bancada, então é realizada a implementação de projeto em bancada.
Power generation from alternative sources is at present the subject of numerous research and development in science and industry. Wind energy stands out in this scenario as one of the most prominent alternative in the generation of electricity, by its numerous advantages. In research works, computer reproduction and experimental behavior of a wind turbine are very suitable tools for the development and study of new technologies and the use of wind potential of a given region. These tools generally are desired to include simulation of mechanical and electrical parameters that directly affect the energy conversion. This work presents the energy conversion process in wind systems for power generation, in order to develop a tool for wind turbine emulation testing experimental, using LabVIEW® software. The purpose of this tool is to emulate the torque developed in an axis wind turbine. The physical setup consists of a three phase induction motor and a permanent magnet synchronous generator, which are evaluated under different wind speed conditions. This tool has the objective to be flexible to other laboratory arrangements, and can be used in other wind power generation structures in real time. A modeling of the wind power system is presented, from the turbine to the electrical generator. A simulation tool is developed using Matlab/Simulink® with the purpose to pre-validate the experiment setup. Finally, the design is implemented in a laboratory setup.

Abstract:
A project funded by the Southern California Edison (SCE) Company, Research Center of Irwindale, California, has supported the development of a performance and parameter prediction software program for use during the refurbishment of large synchronous machines, turbine generators, and synchronous condensers. The computer program was developed for SCE to allow user friendly input of a machine's physical parameters such as pole/field/winding/stator dimensions, type of steel, and other related information in order to calculate the machine's reactances, time constants, and performance curves. The program also allows some degree of design calculation to be performed in order to meet certain design criteria where appropriate. The theory behind the calculations upon which the electrical calculations are built is obtained primarily from literature published in the early 1950's. Since that time, however, machine design has progressed into ever larger generators, most often in the hundreds of Megawatt range with some units exceeding one thousand Megawatts. This size increase has established the practice of winding the stator coils into parallel circuits to maintain acceptable flux and generated voltage levels. These design practices justify a re-examination of the traditional methods used to calculate a machine's reactances and time constants. Accordingly, the use of parallel circuits in the stator winding and their effect on machine parameters has not, to this author's knowledge, been addressed in public literature. These issues are exam fled and modifications to the traditional formulas have been derived for the reactances along with the process of carrying out the calculations on a per pole basis. In addition, the calculation of the parameter and performance equations of a machine are suitable for implementation on a computer due to the length and often iterative calculation procedures. The procedures used to calculate the capability and saturation curves directly from the machine's physical dimensions are developed. During development of the program a forty megawatt generator was measured in order to test and debug the program. Results of this test case are presented and compared to test values obtained at the time of the generator's installation.

Abstract:
Brushless Doubly Fed Machines (BDFM) have potential advantages in variable speed generation and adjustable speed drive applications. The most significant of these advantages is a reduction in the power electronic converter rating, and therefore a reduction in overall system cost. Presently, efforts are being directed at optimizing the design of the BDFM and investigating areas of commercial feasibility. One possible aid in the investigation of design alternatives is finite element analysis. Finite element analysis is a numerical method for determining the field distribution in a dimensional model. Finite element techniques have been successfully used for some time in the design of induction, reluctance and permanent magnet machines. However, the characteristics of the BDFM require adjustment of the finite element design procedure used for conventional singly-fed induction machines. In this thesis, a three-dimensional finite element design procedure for modeling the BDFM has been developed. This design procedure avoids the difficulties previously associated with finite element modeling of the BDFM. The three-dimensional finite element design procedure developed in this thesis was used to model the 6/2 pole 5 horsepower BDFM laboratory machine. From the simulation results, the induced currents in the BDFM rotor bars were calculated. In the course of investigating three-dimensional finite element analysis for the BDFM, two different commercially available finite element analysis software packages were examined and tested. The first was Maxwell 3D Field Simulator produced by Ansoft Corporation, and the second was MSC/EMAS (Electromagnetic Analysis System) and MSC/XL by MacNeal-Schwendler Corporation. These two software packages are compared and their advantages and disadvantages/limitations are discussed. A tutorial for setting up and solving a three-dimensional BDFM model using MSC/XL and MSC/EMAS is presented. This goal of this tutorial is to guide a new user of MSC/XL and MSC/EMAS through the creation, setup, simulation, and analysis of a BDFM model. This tutorial contains condensed information included in the MSC/XL and MSC/EMAS program documentation provided by MacNeal-Schwendler. In addition, modeling techniques particular to the BDFM, which are not included in the program documentation, are described. This tutorial is applicable only to those individuals interested in learning how to use MSC/XL and MSC/EMAS in order to simulate a BDFM model.

Abstract:
It must have been entirely coincidental that two remarkable linguistic movements both occurred during the mid 1950s—one in the realm of natural language, the other in the domain of the artificial; the one brought about largely by a young linguist named Noam Chomsky (1928–), the other initiated by a new breed of scientists whom we may call language designers; the one affecting linguistics so strongly that it would be deemed a scientific revolution, the other creating a class of abstract artifacts called programming languages and also enlarging quite dramatically the emerging paradigm that would later be called computer science. As we will see, these two linguistic movements intersected in a curious sort of way. In particular, we will see how an aspect of Chomskyan linguistics influenced computer scientists far more profoundly than it influenced linguists. But first things first: concerning the nature of the class of abstract artifacts called programming languages. There is no doubt that those who were embroiled in the design of the earliest programmable computers also meditated on a certain goal: to make the task of programming a computer as natural as possible from the human point of view. Stepping back a century, we recall that Ada, Countess of Lovelace specified the computation of Bernoulli numbers in an abstract notation far removed from the gears, levers, ratchets, and cams of the Analytical Engine (see Chapter 2, Section VIII ). We have seen in the works of Herman Goldstine and John von Neumann in the United States, and David Wheeler in England that, even as the first stored-program computers were coming into being, eff orts were being made to achieve the goal just mentioned. Indeed, a more precise statement of this goal was in evidence: to compose computer programs in a more abstract form than in the machine’s “native” language. The challenge here was twofold: to describe the program (or algorithm) in such a language that other humans could comprehend, without knowing much about the computer for which the program was written—in other words, a language that allowed communication between the writer of the program and other (human) readers—and also to communicate the program to the machine in such fashion that the latter could execute the program with minimal human intervention.

Abstract:
The 10 MW High Temperature Gas-cooled Reactor-Test Module (HTR-10), which was designed, constructed and operated by the Institute of Nuclear and New Energy Technology (INET) of Tsinghua University, is the first High Temperature Gas-cooled Reactor (HTGR) in China. Stepping into the commissioning phase in April, 2000, the HTR-10 attained the first criticality in December, 2000 and achieved its full power operation in January, 2003. Up to now, the HTR-10 has been successfully operated for more than ten years with different power levels. During the relatively long period of commissioning and operation, various kinds of tests were carried out on this reactor. Within the scope of this paper, the commissioning stage, the operation history and the test implementation of the HTR-10 are briefly summarized. At this stage, the HTR-10 is the only pebble bed HTGR under operation in the world, so the measured data from this reactor are extremely valuable for verifying the inherent safety features incorporated in small modular HTGRs as well as for testing the computer programs employed in the HTGR design process. With the purpose of ensuring the code credibility, validation work using the HTR-10 operation and test data has been performed for several years in INET. What is more, these data were partly shared with different countries through some collaborative research projects related to code development and assessment. In this paper, progress of the HTR-10 measured data utilization is reviewed. Meanwhile, existing problems observed from the code-to-test as well as code-to-code comparisons are pointed out. In addition, possible reasons of such problems are discussed in detail.
