中文摘要：
磁流变阻尼器（Magnetorheological Damper，MRD）与隔震垫组成的半主动隔震系统能有效地改善被动隔震系统的性能，消除隔震层因过大变形产生的不利影响。基于市场机制的控制（Market-Based Control，MBC）策略是一种利用自由经济市场来模拟控制系统，用销售商和消费者来代替能量源系统和受控系统，并应用市场中商品的供需规律来完成系统控制能量的分配，实现对受控系统有效控制的策略。本文将MBC策略应用于此种半主动隔震系统，提出了相应的控制策略，实现对MRD电压的实时有效控制。算例分析表明，采用此策略能充分利用MRD的变阻尼特性，使结构振动控制效果显著。
英文摘要：
The semi-active isolation system, which consists of magnetorheological dampers and isolators, can effectively improve the performance of passive isolated system and has the ability to avoid the bad influence caused by the excessive deformation of the isolated layer. MBC strategy is an effective control approach that uses the liberal economy market to simulate the complex control system, where the energy system and the controlled system are replaced by seller and consumer, and applies the merchandise＇ s supply-demand （S-D）law to distribute the control energy. In the paper, a semi-active control strategy for this semi-active base-isolated system using MBC strategy is proposed to actualize the effective control of the MRD＇ s voltage. Numerical simulation resuhs show that the proposed scheme can make the best of the MRD＇ s variable-damping characteristic, and can significantly mitigate the response of the structure.
