The adaptation to vector control theory is so generalized that it is widely used for implementing the high-performance of AC machine Nowadays, One-Chip microprocessors or DSP chips are being well-used to implement Vector Control Algorithm. DSP Chip have less flexibility for memory decoding and I/O rather than One-Chip microprocessor so that is requires more additional circuit and high cost And the past One-Chip micro processors have difficult of implementation the complex algorithm because of small memory capacity and low arithmetic performance Therefore we implemented the vector control algorithm of PMSM(permanent Magnetic synchronous Motors) using 80296SA form intel?? , which have many features as 6M memory space, 50MHz clock frequency, including memory decoding circuit and general I/O, Special I/O(EPA, Interrupt controller, Timer/Count, PWM generator) which is proper controller for the complex algorithm or operation program requiring do much memory capacity, So in this paper we fully digitized the vector control of PMSM included SVPWM voltage controller using the intel 80926SA

산업 현장에서 널리 사용되고 있는 권선형 유도전 동기의 완전한 벡터제어를 속도 검출기를 사용하지 않고 슬립 주파수를 추정하여 구현할 수 있는 알고리즘을 제안했다. 기존의 센서리스 벡터제어 알고리즘 은 전동기의 저항의 변동에 대하여 아주 민감하지만 본 논문에서 제안된 알고리즘은 여자 전류 및 슬립주 파수 측정에 전동기 2차 저항을 필요로 하지 않아 전동기 정수 변동으로 인한 벡터제어의 불완전함을 제 거했다 시abf레이션을 통하여 제안된 알고리즘의 우 수한 특성과 그 타당성을 확인을 하였다 .

From the age of Three kingdoms (The time when Korea was divided into three parts, under the sovereignties of Koguryo, Paekche, and Silla, A.D. 2C-7C) throughout Koryo and Yi dynasties,(the two most popular and conspicuous Korean, women's hair style were) $quot;Eunjun Meuri$quot; and $quot;Ttaeun Meuri.$quot; However, along the tendency of sumptuous moods of the society the extravagant and luxurious hair styles of the women during the middle of Yi Dynasty eventually brought on the public criticism in connection with their social and -moral abuses. It was the middle of Yi Dynasty when such prevalence, of unpleasant customs reached to its climax. In that period of Korean history there was a remarkable historical effort concentrate-1 in pursuing particular Korean value and performance through the critical spirit against the reality. In such social thoughts, the increasing tendency of luxury of women's hair style at last caused to the enforcement of Proclamation of Prohibiting Women's Wig by King Youngjo and King Jeungjo (A.D. 1725-1800). Due to this government regulation, the hair style of women, $quot;Eunjun Meuri$quot; was replaced by $quot;Jok Meuri.$quot; The hair styles of the women during the period of middle and latter part of Yi Dynasty were variously beautified, and they may be classified into $quot;Daesoo,$quot; $quot;Ceudumi,$quot; $quot;Euyumi,$quot; $quot;Eunjun Meuri,$quot; $quot;Jok Meuri,$quot; $quot;Jojim Meuri,$quot; $quot;Saeng Meuri,$quot; $quot;Chopji Meuri,$quot; and $quot;Ttaeun Meuri,$quot; etc. The hair styles were chiefly purposed and adapted to as follows: $quot;Daesoo$quot; and $quot;Geudumi$quot;: A formal hair style only restricted queen and the court ladies for their ceremonial purposes. $quot;Euyumi$quot;: The particular hair style applied to married princesses, wives of royal families and wives of high ranking civil and military offcials. $quot;Eunjun Meuri$quot;: A basic hair style of Korean women broadly applied with wigs of natural human hair braided and rolled up on the top of the head. $quot;Jok Meuri$quot;: This hair style was created in place of $quot;Eunjun Meuri$quot; which was prohibited by the government in a measure against the luxurious moods of the society during and after middle part of the dynasty. The style was formed by braiding hair plait and rolled it up to place at the rear side of head fixed by hair pin. Coming into latter part of the dynasty, this hair style became gradually popular among the distinguished ladies of the court and noble lines, and eventually become general hair style of Korean women. $quot;Jojim Meuri$quot;: This is a kind of wig chiefly used by the court maids. The style was a form of $quot;Jok Meuri$quot; for the read- side of head and pinned on the top of head a marked ribbon indicating her position (or rank, status.) $quot;Chopji Meuri$quot;: This hair style indicates the women's ranks applied to queen and wives of royal families and high ranking officials. The style was $quot;Dare Meuri$quot; and queen attached on her hair of head with a mark of Chinese Pheonix while others wore frog marks on their hair of heads. $quot;Saeng Meuri$quot;, Originally this hair style was commonly used by maidens. However, coming into latter part of the dynasty the young court ladies applied it for their hair style. The style showed as a braided plait rolled up and placed on the top of head wearing a purple hair ribbon. $quot;Ttaeun Meuri$quot;: This is the basic and most popular hair style of Korean maidens. The style of hair is a pigtail extended long on the backward, braiding a plait of hair. Other hair styles: The old records of Korean women's hair style:? furthers $quot;Tamakye,$quot; $quot;Kulkye,$quot; and $quot;Nangja Ssangkye,$quot; etc., but it is not apparent to know whether they were popular or not in Korea. However, one thing is apparent that the style weree once prevailed in China, therefore it might had been applied among Korean women in the past. The variously typed hair styles of Korean women as described above had been simplified gradually toward the end of Yi Dynasty. By then, the beauty of hair styles of those wives of royal families and high ranking officials become rather simplified while queen's hair style for ceremonial purpose remained unchanged. Usually, the hair style appled in ordinary daily life of not only common women but also that of queen was $quot;Jok Meuri.$quot; The tendency toward the simplification of Korean women's hair style in those days was likely due to the serial government effort in regulations on the hair styles and difficulties of the economical situations of the end of Yi Dynasty. Summing up, it can be classified into two styles of hair of Korean women since the age of Three Kingdoms that the married women applied to $quot;Eunjun Mcuri$quot; while that of maidens were $quot;Ttaeun Meuri$quot; braided and pig tailed in one or two plaits.
