摘要

基于频域内遗传优化和时域分析，对主动调谐质量阻尼器（ATMD）的反馈系数进行了深入研究。通过考察最优化设计ATMD的结构层间位移控制有效性、楼层绝对加速度控制有效性及控制系统冲程和峰值控制力，发现在参数合理和控制力相近情况下，负标准化加速度反馈增益系数（NAFGF）ATMD比正标准化加速度反馈增益系数（NAFGF）ATMD具有更好的控制有效性。

Abstract

Based on both genetic optimizations in the frequency domain and time domain analysis, a thorough inquiry into optimum feedback factors of active tuned mass damper (ATMD) has been made in the present paper. We find out that the control effectiveness of the ATMD with the negative normalized acceleration feedback gain factors (NAFGFs) is better than that with positive NAFGFs in conditions of the reasonable parameters and approximately equal control forces via evaluating the effectiveness of the storey drift control, effectiveness of the floor absolute acceleration, strokes and peak control forces.
