적응 퍼지 관측기를 이용한 비선형 시스템의 강인한 제어기 설계
류태영,현창호,김은태,박민용 한국지능시스템학회 2006 한국지능시스템학회 학술발표 논문집 Vol.16 No.1
본 논문에서는 외란을 갖는 불확실한 비선형 시스템을 제어하기 위하여 H<SUP>∞</SUP>제어를 이용한 강인 간접 적응 퍼지 관측기를 설계하여 상태변수를 관측하고 외란관측기를 설계하여 시스템의 외란을 제거하는 강인한 제어기를 구성한다. 제안된 외란관측기는 시스템과 외란의 대역폭보다 큰 궤환 이득을 가짐으로써 기존의 역플랜트 모델 또는 퍼지 기반의 외란관측기 보다 간단한 구조를 가지고 외란과 시스템 모델링 오차의 합을 관측해 낼 수 있다. 본 논문에서는 도립진자 시스템의 모의실험을 통하여 관측기, 외란관측기와 제어기의 성능을 평가한다.

The modern history of Israel was a history of Jewish immigration to Palestine and their development of the society of Erez Yisrael. The wave of Jewish immigration was started in 1880's from Russia, Eastern Europe and all over the world initiated by the Zionist Movement and the Hovevei Zion Movement. Before the State of Israel, all five waves of immigrations brought the Jewish people to Palestine about 450,000 immigrants. These inmmigrants looked on land settlement as a primary condition for the rejuvenation of the Jewish people. During the biginning of the immigration, the first Jewish agricultural settlements, such as Petah Tikvah, Rishion Le Zion, Rosh Pina, Zikhron Yaakov, and Hedera, were established and the foundations of the Yishuv were alid. After the wave of Second Aliyah, new methods of land settlement (kibbutzim) were adopted, and the foundation was laid for the whole Palestine and the first mixed farming villages (Moshav Ovedim) lvere established. The first Jewish agricultural settlement in Palestine was begun in the 1870's by a small nucleus of the population in Palestine. These days, there are 227 kibbutzim with 91,700 total population and affiliated with the six federations of kibbutz movements. On the other hand, in the moshav movement, there are 349 rnoshavim with 127,900 total population and affiliated with the seven federations of moshav movements. Between the moshav movement and the kibbutz movement, there are sandwitzi a type of settlement, between moshav and kibbutz, moshav shittufi. The moshavim shittuffyyim movement also have 6,500 population with 29 settlements. (see table 21.) The moshav movement was rapidly developed after the State of Israel more so than the kibbut3 movement because the mass of immigrants after the founding of the State of Israel were from many different sources. These immigrants were more like capitalist or less ideological than the immigrants who came before the statehood. However, both of them have contributed to establishment the State of Israel and the development of farming in Israel. Recently, the kibbutz movement has decided to establish the industrial factories in the kibbutzim. These days, most of the kibbutz, have industrial factories, sometimes with the hired labourers from outside. I think kibbutzim will be develop very well and the kibbutzim will become larger industrial groups, and will be very rich villages. On the other hand, the moshav settlements can not be the industrial villages because of their structure of small holders' settlement. However, to the other developing countries, the applicability of moshav principles for agricultural development and for the development of rural societies is usefull. Therefore, this paper discribed and analysed the moshav movement in depth as a considerable countermeasure to the developing countries from Israeli moshav settlement principles.

사회학을 전공한 필자로서는 ‘유대인의 가정교육’에 대해 말하는 것이 적당하지 않을런지도 모르겠다. 그러나 필자는 이스라엘에서 7여년 동안 그 곳의 학생들과 함께 공부했었고, 학위를 받은 후에는 국립 벤구리온대학에서 강의를 맡아 교수직에 머물러 있은 적이 있다. 또한 나의 두 자녀를 이스라엘에서 교육하면서 학부모로서의 이스라엘의 교육을 다양하게 경험할 수 있는 기회를 가졌었다. 이러한 경험을 토대로 교육학적인 측면에서가 아니라 필자 자신이 보고, 느끼고, 체험했던 사실을 기초로 하여 유대인의 교육에 대해 말해보고자 한다.
