【摘要】 多市场竞争机制控制策略(Multi-Market Based Control,简称MMBC)是一种分散控制算法。文章利用有限单元法,在MATLAB工作环境中建立某空间网壳结构的有限元模型,以磁流变阻尼器为半主动出力装置,结合MMBC控制策略和半主动控制率,实现空间网壳结构在地震作用下的结构半主动控制,分析比较了无控与控制状态下结构的振动响应。结果表明,多市场竞争机制策略可以有效应用于空间结构的振动控制中,具有良好的减振控制效果。更多还原

【Abstract】 Multi-Market based control(MMBC) method is a kind of decentralized control algorithm.A reticulated shell structure model is built using finite element method in MATLAB environment and Magneto-rheological damper which selected as semi-active control device to realize semi-active control under earthquake combining MMBC method and semi-active control law.Vibration response is analyzed and compared between no-control and under-control.Results show that: it is effective to apply MMBC method to the vibration control of space structure and has better damping effect.更多还原
