Abstract

Aiming at severe slewing vibration in ultra-long flexible boom，the mechanism identification and active control of the slewing vibration was considered. Firstly，The simplified dynamical model of slewing boom system was established based on the finite element method，and the slewing characteristics of the model was analyzed. Secondly，The active vibration control method is presented, which combining the algorithms of modal filtering and optimal pole assignment. Finally，The test platform based on NI instrument was implemented and the active vibration control experiment was carried out. The experimental results showed that the damping ratio of the controlled slewing system increase and the slewing vibration of boom tip decrease obviously，which validating the effectiveness of the proposed method.

Key words
