Abstract

In this paper, is proposed an anti-swing control algorithm for the automation of overhead crane. The algorithm consists of three parts, the FCL with compensatory FLC which generates acceleration, velocity and position reference to reduce swing angle and acceleration feedback controller which feedback control errors. Especially the algorithm dose not need angular sensor which detect swing angle of payload and requires high cost. By the simulation study and experiment with prototype crane, we showed the usefulness of the proposed algorithm.

천정크레인 설비의 자동화에 사용될 수 있는 반진동 제어알고리즘을 제안하였다. 제안하는 제어알고리즘은 1) 복잡한 비선형계통 제어에 유용한 것으로 알려진 보상 FLC를 갖는 FCL, 2) 화물의 진동을 적게 하도록 가속도, 속도, 위치 기준 궤적을 발생하는 기준패턴발생기, 3) 속도, 위치 오차를 궤환하는 가속도 궤환제어기로 구성된다. 특히, 제안한 알고리즘은 화물의 진동각 정보를 제어에 활용하지 않으므로 고가의 진동각 센서가 필요 없다는 특징을 갖는다. 시뮬레이션에 의한 연구와 모형 크레인에 대한 실험 연구에 의해 제안하는 알고리즘의 유용성을 보인다.
