The present invention is to provide a method for damping residual vibration of a tower crane by a residual vibration damping device of the tower crane. According to an embodiment of the present invention, a method for damping residual vibration of a tower crane comprises the steps of: receiving length information of a hoisting rope extended from a trolley by the load; calculating in real time a natural frequency and an attenuated natural frequency of the hoisting rope based on the received length information of the hoisting rope; generating an anti-vibration motion signal based on the calculated natural frequency and the attenuated natural frequency; and controlling at least one of a hoist driving unit, a trolley driving unit, and a slewing driving unit based on the generated anti-vibration motion signal.

    본 발명의 일 실시예에 따른 타워 크레인의 잔류진동 감쇠 장치에 의한 타워 크레인의 잔류진동 감쇠 방법에 있어서, 하중에 의해 트롤리로부터 연장된 호이스팅 로프의 길이 정보를 수신하는 단계; 상기 수신한 호이스팅 로프의 길이 정보를 기초로 상기 호이스팅 로프의 고유진동수 및 감쇠고유진동수를 실시간으로 산출하는 단계; 상기 산출된 고유진동수 및 감쇠고유진동수를 기초로 반진동 모션 신호를 생성하는 단계; 및 상기 생성된 반진동 모션 신호를 기초로 호이스트 구동부, 트롤리 구동부 및 슬루잉 구동부 중 적어도 어느 하나를 제어하는 단계를 포함하는, 타워 크레인의 잔류진동 감쇠 방법을 제공하고자 한다.
