This paper presents an implementation of vector control for SMPMSM using model based controller design in MATLAB/SIMULINK. The model based controller design enables fast development of control system for motor by designing controllers and performing simulation on the GUI (Graphic User Interface) platform, converting program code directly into real-time programs, and then performing tests for the responses from controllers. The controller is designed as PI controller for speed and decoupling PI controller for current. And PWM used space vector modulation method using offset voltage and system stability is also secured by close magnitude overmodulation method, maintaining dynamics of load when it overmodulation. The validity of vector control implemented is verified through simulations and experiments.

For the construction of thesaurus, a thesaurus management system is needed which can process dynamic variations fast and exactly such as input. correction and deletion of words, and definition of new relationship between words. In this paper, I developed a thesaurus management system based on the object-oriented technique and GUI(graphic user interface) screen, and to enhance the effectiveness of information retrieval. I put emphasis on the expansion of synonym, English and Korean words containing the same concept.

Primary purpose of the system developed in this study is 3-D seismic data processing system for subsurface structure imaging and this system is developed in PC based on Linux for lower-cost computer. Basic data processing modules are originated from SU (Seismic Unix) which is widely used in 2-D seismic data processing and auxilious modules are developed for 3-D data processing. The system which is constructed by using these data processing modules is designed to GUI (Graphic User Interface) in order that one can easily control and for this purpose, GTK (Gimp Tool KiT) conventionally adapted in producing Linux application.

The preprocessor - solver - postprocessor software for 2D/Axisymmetric CSCM Upwind Flux Difference Splitting Navier-Stokes code has been developed for undergraduate educational purpose. This computational fluid dynamics (CFD) software allows students to setup, solve, visualize and control dynamically server for their own fluid problems via Internet. The preprocessor Is capable of generating geometry and grid, initial solution data and required solver control parameters. The postprocessor shows vector plot and contour plot with different options while residual plot shows root-mean-square (RMS) error history graphically and retrieves the data from solver interactively. Special feature of the preprocessor is grid generation part which is based on MFC/Visual C++ application and FORTRAN single block grid generator process. Many users can access solver via Internet from client computers and solve desired problems using locally installed pre- and postprocessor and remote powerful solver part.

In this study, a performance simulation program for a turbojet engine using SIMULINK, which can provide the GUI(Graphic User Interface) environment, was newly proposed. Performance analysis results using the SIMULINK performance program were compared with them using the FORTRAN performance program that was previously developed. According to comparison result, it was noted that performance analysis results between two programs have little bit big difference. This difference seems to be due to different component matching algorithm at each program, it will be improved later.

This paper presents a method for measuring and analyzing strains in sheet metal forming by stereo vision system. A better understanding and evaluation of the formability can be achieved by analyzing stain distribution in deformed sheet metals. By means of image processing technique, it is possible to get strain distribution efficiently. For measuring strain automatically and accurately, algorithms for camera calibration, grid detection, stereo matching and strain analysis has been developed and verified by experiments with GUI(Graphic User Interface).

The objective of this study is to develop a NGIS-GUI (National Geographic Information System-Graphic User Interface) system for the computation of peak discharge at drainage basin outlet. The developed system is composed of GIS data extraction module, peak flow computation module and output display module. The selected study area is the Sungjun reservoir area near the Milyang, Kyungnam province and the peak flows depending on various recurrence intervals are computed and graphically displayed. The developed system will be useful for the scientific water flow management in the study area.

LIN(Local Interconnect Network) 통신은 CAN(Controller Area Network) 통신과 더불어 차량용 통신으로 많이 사용되고 있다. LIN 통신은 필요 성능의 수준이 높지 않은 장치 및 시스템이나 비용의 경제적인 측면에서 CAN 통신의 하부버스로 많이 사용되며 LIN 노드에 개수도 점차 늘어나고 있다. 그렇기 때문에 LIN통신으로 시스템 제어 및 모니터링 프로그램을 GUI(Graphic User Interface)로 제작한다면 시스템 상태의 디스플레이 및 모니터링이 수월해진다. 함수와 GUI로 제작되는 LabVIEW는 다른 텍스트 언어기반 개발 프로그램에 비해 설계 시간 단축 및 사후 관리도 쉽다는 장점이 있다. 본 논문에서는 LabVIEW로 제작한 IBS 모듈 기능 검사 장비개발을 통해 LIN 통신으로 송수신되는 데이터를 확인하고 모니터링, 그리고 설계가 용이하다는 것을 소개하고자 한다.

This paper proposes an algorithm of CAD data extraction for the computer controlled making system. In general logo is directly designed at the marking controller, but that is not an effective method because of the very limited working area. In this paper, for the data extraction we used a general PC and Auto CAD for logo design, and developed the software with GUI(Graphic User Interface) method. Then the data is transferred to the marking controller for marking on the object. With experimental result we showed the proposed algorithm to be very effective in the computer controlled marking system.
