| 摘 要： | 提出了基于滚球隔振和换能控制在风荷载激励下的智能控制系统,在结构物的底层采用滚球隔振并实施换能控制,利用滚球隔振大幅度地降低风荷载激励对上部结构的影响,同时发挥换能控制的优点,限制隔振层的相对位移并改善控制效果.建立了该控制系统的数学模型,该模型是非线性系统,有极强的鲁棒性,所以采用模糊控制算法实施智能控制.通过仿真分析研究了该系统的特点和算法的有效性.

| Abstract: | An intelligent structural control system is proposed by employing ball isolation and control with energy transformation in the wind load.Responses of the super structure can be reduced effectively by ball isolated in wind load,while the relative drift of the isolation layer could be controlled and the control performance is improved depending on the merits of the control device with energy transducer. The numerical model about the control system is established. Multi-stage force control was conducted by usi... |
