PI자기동조제어기를 적용한 전류가역쵸퍼시스템의 성능개선에 관한 硏究
강승욱 가톨릭상지전문대학 1997 논문집 Vol.27 No.1
There are two important requirements for high-performance controlled electrical droves ; One is the steady-state and dynamic tracking ability to set point changes, and the other is the ability to recover from load disturbance. Conventional PI/IP controllers for such drives are designed on the basis of local lineaization about an operating point. These controllers are very effective if the load changes are small and the operating conditions don't force the system too far away from the linearizing equilibrium point. The adaptive control strategy which has received wide spread acceptance in the electrical vehicle control is the self-tuning control. This paper describes the design and the implementation of a self-tuning proportional-integral speed controller for a Bilaterial dc chopper based on 16 bits microprocessor.

KCTC 훈련은 실제 전장과 유사한 환경에서 훈련할 수 있는 경험을 제공하며, 훈련 중 MILES 장비를 통해 훈련 결과가 저장된다. 본 연구의 목적은 여단급 KCTC 훈련 결과 빅데이터를 분석하여 보병중대의 공격작전 전투 결과에 영향을 미치는 요인을 분석하는 것이다. 본 연구에서는 보병중대가 연구 대상이다. 모든 보병중대가 같은 임무를 가지고 있다고 가정하고 분석하였던 기존 연구와 달리 각 보병중대의 임무를 구분하여 분석하였다. 이를 위해 각 여단 훈련에 대한 보병중대의 위치정보를 이용하여 임무를 확인하고, 보병중대의 임무별 전투 결과는 군사적 교리를 바탕으로 정의하였고, 전장 상황을 나타내는 설명변수를 생성한 후에 회귀분석을 통해 전투 결과에 영향을 미치는 요인을 분석하였다. 본 연구에서는 훈련부대뿐만 아니라 대항군부대의 공격작전 전투 결과를 함께 분석하여 훈련부대와 대항군부대의 차이를 확인하였다. 이를 통해서 훈련부대와 대항군부대 보병중대의 공격작전 전투 결과에 영향을 미치는 요인을 도출하고, 상호 비교를 통해 훈련부대 보병중대가 공격작전에서 좋은 결과를 내는 데 필요한 요소를 확인하고 함의를 도출하였다. Korea Combat Training Center (KCTC) training provides a valuable opportunity for practical experience in a battlefield-like environment, with training results recorded using MILES equipment. The objective of this study is to analyze the factors influencing the outcomes of infantry company offensive operations by examining the big data generated from brigade-level KCTC training results. The focus of this research is on infantry companies. In contrast to previous studies that assumed uniform missions for all infantry companies and analyzed them collectively, this study distinguishes and individually analyzes the missions of each infantry company. To achieve this, location information for each infantry company during brigade-level training was used to ascertain their respective missions. The combat results for each infantry company's mission were defined based on military doctrine, and explanatory variables representing the battlefield situation were created. Regression analysis was then employed to identify the factors affecting combat results. This study not only analyzed the combat results of training units but also considered those of the opposing forces (OPFOR), allowing for a comparative analysis to reveal differences between training units and OPFOR. Consequently, this research derived the factors influencing the combat results of infantry companies in both training units and OPFOR. Moreover, it identified the essential elements for achieving favorable outcomes in offensive operations by training unit infantry companies through comparative analysis, thus yielding valuable implications.

In this paper, we proposes two phase chopper system with flour. separate groups of D.C motor for regenerative braking. The main circuit consists of four sets of chopping parts, eight diodes and four separate groups of D.C motor. Although the proposed chopper circuit requires more circuit elements than the conventional two phase chopper system with, combined output, it has the following advantages: (1) The region of regenerative braking becomes twice as that of the conventional two phase chopper system. (2)Current division of load becomes equalized. Therefore. it is possible to drive not only series motor but also shunt and separately excited motor (3) The harmonic component of the source current is greatly diminished.

Recently, the speed control of electric motorcar usually adapts the chopper control method by the development of power electronics and semiconductor manufacturing techniques. When the chooper control is adapted to the speed control of electric motorcar. D.C.series motor is mostly used because of the large starting torques and good control characteristics. But with respect to the economy, D.C. separately excited motor with shunt characteristics is profitable because of high adhesivesness and consumption. So, we compare the characteristics of the bilateral variable-ratio chopper controlled D.C. separately exited motor with that of the D.C. series motor theoretically and experimentally, and present the method which is able to simplify the main chopper circuit by selecting among the forward powering, forward regenerative braking, backward powering, and backward regenerative braking only by using the main chopper control signal. Also, control method is studied which has similar driving characteristics to that of the gasoline motorcar.

The catalytic graphitization, crystallization, exothermic, and electro properties of polyacrylonitrile (PAN)-based carbon fibers with and without electroless Ni-P coatings of various heat treatment temperatures were studied. The surface and structural properties of the PAN-based carbon fibers were determined by scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectroscopy, respectively. P content in the Ni-P coatings was measured by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The thermal characterization of the PAN-based carbon fibers was studied by thermo-graphic camera and differential scanning calorimetry (DSC). The electrical conductivity was obtained by measuring the surface resistance with 4-pin probe method.
