Direct-drive robots are suitable to the position and force control with high accuracy, but it is difficult to design a controller because of the system's nonlinearity and link-interactions. This paper is concerned with the study of the force control of direct-drive robots. The proposed algorithm consists of feedback controllers and a neural network. After the completion of learning, the output of feedback controller is nearly equal to zero, and the neural network controller plays an important role in the control system. Therefore, the optimum retuning of parameters of feedback controllers is unnecessary. In other words, the proposed algorithm does not require any knowledge of the controlled system in advance. The effectiveness of the proposed algorithm is demonstrated by the experiment on the force control of the parallelogram link-type direct-drive robot.

최근 고압송전선 시설에 대한 경과지 확보가 점점 어려워짐에 따라 환경 친화적인 콤팩트한 송전탑 설계가 요구되어 지고 있다. 콤팩트한 송전탑용 절연재료로서 폴리머에 관한 많은 연구가 진행되고 있으며, 특히 철탑암의 재료로서 폴리머 재질이 몇몇 선진국에서 적용되어 좋은 결과를 얻고 있다. 그러나 국내에서는 송전용 철탑암에 대한 폴리머 재질의 적용은 미흡한 실정이었는데, 이제는 폴리머에 대한 고강도, 고기능화 기술이 개발되고 있으므로, 이를 송전용 철탑암에 적용하게 되면 급격한 전력수요의 증가에 따른 송전공급의 증대에 민첩하게 대응할 수 있는 방안으로 판단된다. 본 연구에서는 송전탑용 폴리머 절연암을 설계하고, 그것의 전기적 특성을 해석하고, 기존 철탑에 적용한 콤팩트 송전탑을 설계하여 기계적 안정성을 시험하였다. As a right-of-way security for the high power transmission line tower construction is becoming more and more difficult, the friendly environmental compact tower design is required. For a proper insulation for the compact tower, the polymer material are being tried. Some countries has already adapted, in the various polymer application and management data, polymer arm insulator to the transmission tower, and shown a stable operation. However, in our country, the polymer arm insulator has left much to be desired in the installation on the transmission line tower. But polymer material has been developed by high strength and technology and is expected to be used in various electric equipments. The polymer arm insulator is a one of good electric insulation materials to expand the power supply capacity in the rapid power demand increasement In this research, the new polymer am insulator is designed and its electric specifications are analyzed. Its mechanical specifications is verified through the field test on the compact tower which is modified by the polymer arm insulator.

The system consists of two parts : one includes hardwares such as actuators, linear scales and a probe, etc. the other involves softwares for management and control of the system. Compared with existing 3D auto inspection system, this system achieved automatically the inspection. This automatic inspection makes the system have some advantages to reduce a measurement time and to be easily used by operators.

With the latest developments in ICT(Information Communication Technology) technology, research on Intelligent Car, Connected Car that support autonomous driving or services is actively underway. It is true that the number of inputs linked to external connections is likely to be exposed to a malicious intrusion. I studied possible security issues that may occur within the Connected Car. A variety of security issues may arise in the use of CAN, the most typical internal network of vehicles. The data can be encrypted by encrypting the entire data within the CAN network system to resolve the security issues, but can be time-consuming and time-consuming, and can cause the authentication process to be carried out in the event of a certification procedure. To resolve this problem, CAN network system can be used to authenticate nodes in the network to perform a unique authentication of nodes using nodes in the network to authenticate nodes in the nodes and By encoding the ID, identifying the identity of the data, changing the identity of the ID and decryption algorithm, and identifying the cipher and certification techniques of the external invader, the encryption and authentication techniques could be detected by detecting and verifying the external intruder. Add a monitoring node to the CAN network to resolve this. Share a unique ID that can be authenticated using the server that performs the initial certification of nodes within the network and encrypt IDs to secure data. By detecting external invaders, designing encryption and authentication techniques was designed to detect external intrusion and certification techniques, enabling them to detect external intrusions.
