Abstract

This paper suggests a preceding study to introduce implementing problems and improving direction when commercializing a ropeless elevator. In this study, the implementation of the study of pilot systems in order to produce the ropeless elevator and also build a linear velocity sensor, this system is applied to the speed control experiment was investigated through testing. Speed control test is carried out in all track including a curved section. This study verified the feasibility of the ropeless elevator and its drive controller is good enough to be accepted. This study also extracted many more problems that still need to be improved in the future for commercializing such as the sensor, high-performance controller, precision structures, safety devices, efficiency improvements and so on.

본 논문은 로프리스 엘리베이터의 상용화에 앞서 로프리스 엘리베이터의 기반 및 요구기술과 개발 시의 문제점 및 개선방향을 제시하기 위한 선행연구를 제안한다. 본 연구에서는 연구의 구현을 위하여 로프리스 엘리베이터를 소형시스템으로 제작하고 또한 자체 리니어 속도센서를 제작, 본 시스템에 적용하여 속도제어 시험을 통하여 문제점을 검토하고자 한다. 속도제어는 곡선구간을 포함한 전 영역에 걸쳐 수행하였으며, 본 연구의 수행 결과 로프리스 엘리베이터의 실현 가능성을 확인하였으며 구동제어 기술의 만족할 만한 결과를 얻었다. 하지만 현재의 기술적인 수준에서는 상용화를 위해 센서, 고성능 제어기, 정밀 구조물, 안전장치, 효율향상 등 향후에도 더욱 개선되어야 할 여러 가지 문제점도 도출할 수 있었다.
