| 摘 要： | 研究风荷载激励下考虑变时滞空间网格结构的振动控制。在分析结构变时滞产生原因的基础上,基于动态矩阵预测控制算法,构造预测模型和优化策略,提出对变时滞空间网格结构振动控制的改进方法和控制参数选取的基本原则,指出准确预测系统的未来输出、选择恰当的采样周期是实施振动控制的关键因素。以柱面网壳结构为例并选取适当参数,针对变时滞有控与无控的结构振动系统进行风振控制数值分析与比较。研究结果表明:运用该方法对变时滞空间网格结构的振动控制,可获得满意的控制效果。

| Abstract: | This paper was focused on the wind vibration control of Spatial Latticed Structure(SLS) with variable time delay.The composition of variable time delay in SLS was investigated.Based on the dynamic predictive control strategy,the new control model and optimization strategy were constituted,an improved method for the wind vibration control of SLS with variable time delay was put forward,and some principles for choosing control parameters were discussed in details.It is emphasized that the prediction for after... |
