摘要
提出了基于滚球隔震和换能控制的智能控制系统,在结构物的底层采用滚球隔震并实施换能控制,利用滚球隔震有效地降低了地震激励对上部结构的影响,同时发挥出换能控制的特点,限制隔震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,对换能控制装置进行了改进,实现了多级荷载的换能控制,采用遗传算法实施智能控制。通过仿真分析研究了该系统的特点和算法的有效性。
An intelligent structural control system is proposed by employing ball isolation and by controlling with energy transform. Responses of a super structure is controlled effectively by ball isolation, while the relative drift of the isolation layer is alleviated and the control performances are improved depending on the merits of the control device with an energy transducer. A numerical model of the control system is established. An multi-stage force control is conducted by employing the modified control device. Intelligent control is implemented using genetic algorithm. The effectiveness of the control strategy and control system characters is investigated through a sample building simulation.
