  • In this paper, we introduce a new sliding surface adaptable to arbitrary initial conditions. The surface is initially designed to pass given intial errors and subsequently moves towards a predetermined surface via rotating or/and shifting. We call it as a moving sliding surface (MSS) comparing with the conventional ones, for instances, employed by Slotine and Sastry. Using the MSS, it is shown that the tracking is much faster than conventional one without increasing the magnitude of discontinuous control gain. To demonstrate some advantages of the proposed method, we apply the MSS to the path tracking control of a two-degree-of-freedom robotic manipulator subjected to external disturbances.

  • 본 논문에서는 강수량과 자동차 주행속도 등의 환경조건에 따라 와이퍼 속도를 일정하게 적용한 기존의 시스템을 개선하여 운전자의 개인 특성에 의해서도 속도 변경이 가능하게 함으로서 인간에게 조금 더 친밀감을 제공하는 시스템을 구현하였다. 초기 와이퍼 속도는 입력받은 강수량과 자동차 주행 속도로 추론하여 구하였다. 추론된 와이퍼 속도를 운전자의 개인 특성에 따라 변경하고자 할 경우, 해당 음성명령을 입력받아 재 추론하였다. 음성인식을 위해서는 고립단어 인식에 적절한 DTW방식을 사용하였고, 와이퍼 속도는 퍼지 추론을 적용하여 구하였다.

  • This paper presents the design results and characteristic analysis of SRM. For vehicle power supply for adaptable design of the SRM, variable design parameters, such as stator and rotor laminations, winding details, pole numbers, and pole arcs, phases numbers are required. So, in this paper the SRM design results and the comparison of characteristics for vehicle power supply as phases changed are described.

  • In this paper, we drive useful data from 3-D depth information as input using discontinuity boundary or clustering. And using magnitude and direction of z-gradient we classify the data into adaptable primitive types through intrinsic and stochastical processing. After these processing information is reconstructed for forming data base. And make relationship and standard view position for matching.

  • In general, glass has proven to be an effective glazing material, exhibiting extended service lifetime and high solar transmittance while remaining opaque to long wave thermal reradiation. Plastics, which possess higher solar transmittance than commercial glass, are lightweight and also cost competitive with glass. In this paper a survey of various glazing materials is presented, and the comparative analysis of their properties are perform ed in detail with special emphasis on double glazing materials, which can be adaptable to various passive solar systems.

  • We acquired operating data to develop a digital control system adaptable to gas turbine power plant with about 50 to 100MW. We analyzed an existing analog control logic using these data. We developed control application programs for turbine automatic start up. We showed a similar result compared with an existing analog control system by computer simulation.
