포화비선형이 존재하는 시간지연 시스템의 동적 보상 방법

박종구,최종호 성균관대학교 1998 학술회의지원논문목록집 Vol.1998 No.-

본 논문은 포화 비선형이 내재된 시간지연 제어 시스템에서의 리셋 와인드엎에 대처하기 위한 동적 보상방법을 제시하였다. 시간지연요소 만을 포함한 시스템에 대하여 기존의 제어기 설계기법으로 설계된 시스템이 만족할 만한 응답을 보인다고 가정한 상태에서 포화현상으로 인한 성능저하를 완화하는 추가적인 보상기를 설계하였다. 포화요소가 있는 경우와 없는 경우의 제어기의 상태변수 차이를 목적함수로 하여, 이를 최소화하는 동적 보상기를 구했다. 제시된 동적 보상기는 플랜트 및 제어기들의 구성요소로 결정되는 명시적인 형태이다. 제시된 동적 보상기를 포함한 시스템은 전체적 안정도를 보장받는다. 시뮬레이션 예제를 통하여 제시된 보상방법의 효용성을 보였다. A dynamical anti-windup(ARW) method for time-delay control systems with saturating actuators is considered. Under the assumption that a linear controller was designed for the time-delay control system based on the existing design techniques which shows desirable nominal performance, an additional compensator is incorporated to provide a smooth performance degradation due to the control input saturation. By regarding the difference of the controller states in the absence and presence of saturating actuators as an objective function, the dynamical compensator which minimizes the objective function is determined explicitly. The proposed dynamical compensator is the closed form of the plant and controller parameters. The proposed method not only provides smooth performance degradation, but it also guarantees the total stability of the resulting systems. An illustrative example is provided to show the effectiveness of the proposed method.

Computer Application Program의 運用에 關한 硏究 : Linear Progromming을 中心으로

박종구 圓光大學校 1983 論文集 Vol.17 No.2

Mathematical Optimization is any mathematical technique for datermining the optimum use of various resources to attain a particuler objective (such as mimimum cost of maximum profit) when there are alternate use for resources. Iiner programming is the most widely used of these techniques and has been used to allocate, assign, schedule, select, or evaluate the use of limited reseurces for such jobs as blending, mixing, cutting, trimming, bidding, pricing, purchasing, planning, and the transportation and distribution of raw materials and finish products. the purpose of this paper is to develope an alloy blending for the linear propramming. first, model was set up. second, the model was changed to LPS model to formulate into input data Explanation was, therefore, made with respect to Control card and card deck structure in order to identify scope of research on report reading which relate to output of LP solution. In consideration of maket cost changes, an investigation was made with respect to card deck structure, input data, control card and report reading into output in order to formulate into cost change. An investigation was made concerning card deck structure, input data, control card and report reading into output in order to formulate the second LP solution report which utilize the rest part of raw materials after initial alloy blending. the final of main subject (7 and 8) contains a description of the system, the machine configuration requred, and limitson problem size. in this research, we provide a discussion of a basis for the development of a LPS model. Furthermore, an attempt was made to approach both developed and undeveloped program which could contribute to the new LP user.

임의의 이산 포화 제어 시스템에 적용가능한 정적 리셋 와인드엎 방지 방법

박종구 成均館大學校 科學技術硏究所 1997 論文集 Vol.48 No.1

This paper presents an anti-reset windup (ARW) compensation method for discrete-time saturating control systems with multiple controllers and/or multiloop configuration, which can be generalized to arbitrary control system structures. The proposed ARW method is motivated by the concept of equilibrium point. The design parameters of ARW scheme is derived explicitly by minimizing a reasonable performance index. In the event of saturation, the resulting dynamics of compensated controller reflects the dynamics of linear closed-loop system. The proposed method guarantees the total stability of resulting control systems under a certain condition. An illustrative example is given to show the effectiveness of the proposed method.

정적 및 동적 포화 보상 방법을 사용한 제어 시스템의 견실성 해석

박종구 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.2

This paper studies the robustness of saturating systems containing anti -reset windup (ARW) schemes. The schemes under consideration are a static feedback method based on equilibrium point matching concepts and a dynamic feedback method which solves the state-positioning problem. It is shown that saturating systems with plant uncertainties are totally stable provided that the plant remains in open-loop stable. Two ARW schemes show performance robustness to a certain extent since modeling errors take place mainly in the high frequency range.

상온보관이 가능하며 사용이 편리한 DNA Size-Marker와 저분자량의 DNA 계측을 위한 Size Marker용 플라스미드 개발

박종구 啓明大學校 醫科大學 1998 계명의대학술지 Vol.17 No.4

기존의 수입된 핵산 size markers는 dry ice에 넣어져서 운반되므로 매우 고가이다. 따라서 상온에서 보관될 수 있는 방법을 모색하던 중, 많은 물질의 경우 건조상태를 유지할 때 높은 안정성을 유지한다는 점에 착안했다. DNA는 매우 안정한 물질이므로 그 가능성은 더욱 높다고 가정했다. DNA size markers에 첨가되는 요소를 모두 혼합한 다음 동결건조를 시도해 보았다. 상온과 빛, 상온과 빛 차단 그리고 4℃와 빛 차단의 조건으로 60일간 방치한 후 건조 전 부피의 증류수로 건조체를 이용하여 전기영동 양상을 비교한 결과 DNA size markers의 양 및 질에서 큰 변화가 없었다. ΦX174 phage DNA는 double strand로 분기가 쉽지않으며 phage의 대량배양도 용이하지 않다. 이러한 문제점을 해결하기 위해 기존의 플라스미드를 변조하여 ΦX174 HaeIII 절단체와 유사한 DNA 분리 양상을 나타내도록 하였다. 개발된 새로운 플라스미드는 column chromatography를 사용하여 분리한 후 제한효소에 의해 효과적으로 절단되었다. 종합하면, 새로운 보관방법과 플라스미드의 개발은 국내에서 양질의 ΦX174 DNA size markers를 적정한 원가로서 개발할 수 있음을 나타낸다. Molecular biotechnology is a broad research and development principle encompassing basic research as well as applied industrial developments. Biotechnology is expected to become one of the most important research and development sectors in the next century, but the domestic support industry for the field is severely underdeveloped and at best in its infancy. DNA size marker is frequently employed during research in a purpose of extrapolating the relative size of a DNA fragment or measuring the amount of DNA loaded a sample. However, DNA size marker is not developed for commercialization domestically. Further, liquid suspension containing DNA size marker needs to be kept at a low temperature during storage and shipping. In an attempt to maintain the DNA samples at room temperature for extended period of time, lyophilization of DNA with addition of a nuclease inhibitor was studied. Hae Ⅲ digest of ΦX174 phage DNA has been a useful size marker for low molecualr weight DNA molecules, but the double strand RF form of the phage DNA requires laborious procedures for cell culture and purification. A new plasmid was constructed to generate band patterns which can substitute the Hae Ⅲ digest of ΦX174 phage DNA for a comparable purpose. Gel staining dye was also added to the lyophilized DNA to provide additional convenience such that DNA size marker was ready for use by simple reconstitution of distilled water. DNA size marker appears to be advantageous for development as one can judge the quality of the product by direct observation.
