The aims of this study is to develop working robot for a installed trolley cable of an electric train and objective of this paper is to implement mobile control of working robot. In this paper an approach to method for scheme of a mobile control system is presented in a dynamic hybrid velocity/tension control of working robot. The working robot is composed the velocity and tension controllers using the concept of two-degrees-of-freedom servo-controller. This robot moved at same time a certain distance to constrain a constant tension and installed a trolley cable of an electric train. To move the robot the velocity control system have design and implemented. Simulation and experimental results are presented to illustrate the validity of designed mobil scheme.

As a stringing troy wire is installed by manual operation, it is necessary to scheme the automatic system for stringing troy wire. To accomplish a task of this kind, in this paper an approach to designing controllers for the hybrid Position/Tension control of a stringing troy wire is presented. Position control system is designed based on equation of dc motor and motion equation of robot, it is controlled by feedback with a detected speed dc motor. Tension control system is designed based on equation of ac servomotor for generating torque and dynamic equation of a troy wire, it is controled by feedback with a detected tension. The control parameters is determined by simulation in independence operation of each system. To suppress a mutual interference that the disturbance occur in operating of two task at same time. Dynamic hybrid control is proposed by feed forward compensator with a disturbance accelerator and a step torque at start. The operation of proposed system is simulated and experimented, results is verified the utilities.

고온 초전도체를 이용한 에너지 저장장치는 종래의 저온 초전도체를 이용한 장치에 비해 효율이 높고, 설치 면적이 작으며, 환경 친화적 특성을 갖고 있다. 또한 냉각비용이 저렴하고 저장되는 에너지 밀도가 높다. 고온초전도 선의 성능향상이 가속화됨에 따라 고온초전도 선을 이용한 초전도 전력기기의 개발이 활발히 이루어지고 있다. 하지만 초전도 선이 구리선에 비하여 고가라는 단점이 여전히 문제가 되고 있다. 가격적인 측면에서 선의 사용량을 줄이기 위한 대책이 필요하다. 또한 코일의 손실해석은 전력기기의 경제성 여부와 성능향상을 위해 수행되어야 할 중요한 연구 분야 중 하나이다. 본 논문에서는 초전도 선으로 권선한 코일의 자장분포 및 인덕턴스를 유한요소법(FEM)해석을 통해 확인하였으며, 솔레이드 코일, 팬케이크 코일, 트로이달 코일의 저장용량을 결정하기 위해 비교를 통하여 최적의 형상을 도출하였다.
