In this paper, a robust H$\infty$ optimal tuning problem of a structure-specified PSS is investigated for power systems with parameter variation and disturbance uncertainties. Genetic algorithm is employed for optimization method of PSS parameters. The objective function of the optimization problem is the H$\infty$-norm of a closed loop system. The constraint of the optimization problem are based on the stability of the controller, limits on the values of the parameters and the desired damping of the dominant oscillation mode. It is shown that the proposed H$\infty$ PSS tuned using genetic algorithm is more robust than conventional PSS.

각종 성인병 및 항암작용에 탁월한 효과가 입증된 영지버섯을 제빵시 첨가하여 기능성이 부여된 빵을 개발하고자 본 연구를 수행하였다. 영지추출액을 8%까지 첨가함에 따라 쓴맛이 증가하였지만, 1차 발효기간 동안 반죽의 부피는 증가하였고 굽기 손실률이 감소함을 관찰할 수 있었다. 영지추출물을 첨가한 빵의 관능검사결과, 2% 첨가시 유의적인 차이가 나타나지 않았으나, 4, 6, 8%를 첨가했을 때 4%는 보통으로 6, 8%는 대조구에 비해 나쁘게 나타났다. 사진촬영 결과 역시 0, 2% 영지추출액 첨가식빵의 내부조직은 우수하였으나, 4%는 보통으로 6, 8%는 나쁘게 평가되었다. 이러한 사실들로 보아, 일반식빵과 차이가 없는 2% 영지추출액 첨가시 기능성이 부여된 식빵의 제조가 가능하리라 생각한다. The purpose of this study was to develop functional breads added with Ganoderma lucidum (GL) extract which was well known for preventing various adult diseases and cancer. It was observed that bitter taste was increased with up to 8% GL extract while dough volume was increased at the first dough fermentation period and baking loss reduction was decreased. In terms of sensory evaluation, there were not so much significant differences with 2% added GL extract. In 4, 6, 8% added GL extract bread, it was found that 4% was ordinary and 6% and 8% were bad compared to the control bread. The bread with 2% added GL extract was excellent, 4% was ordinary and 6, 8% was badly evaluated in the internal texture. It’s possible to make the functional breads baking with 2% GL extract which is similar to the control breads based on the above results.

Micom is the most powerful and profitable tool for the control of the stepping motor as a small pulse motor. In this paper, it is reported that a series of controll programs, that is, the basic program and the programs for the C. W. and C. C. W. rotations and the limited operations, are developed. And the conclusions through these experiments have been obtained as follows. 1) The drive of the stepping motor is not only excution by Micom pulses, but the finding of the 1 phase, 2phase or 1-2 phase excited output is depended upon the instruction of out port. 2) The sequential control of the exciting phase and the C. W. and C. C. W. rotations of the Rotor through the shifted Accumulator Register inside C P U is excuted easily, and the developements of the control programs and the expansion of the Buffer Memory space make the limited operation and the speed control possible. 3) Ultimately, by the closed loop drive of he stepping motor, when the patterns of the arbitrary selected step accelerations, constant speeds, decelerations and stop are memorized in the Micom Kit, the tracking operation of the open loop drive is possible.

A newly derived O₂ Saturation Model which can adapted to the design and study of Artificial Lung and Blood Gas Calculator etc. is introduced on the of Electrical Equivalent Circuits. The presented 4 stage and 2 stage RC circuits have good correlations with actual chemical reactions of Hemoglobin and Oxygen. However from the results of computer simulations, 2 stage equivalent model is more accurate than 4 stage and conventional O₂ saturation models.
