摘要

基于阻尼力双向调节MR阻尼器的三状态出力特性,结合一体育馆屋盖结构,针对传统半主动开关控制算法提出了改进的半主动中级开关控制算法和半主动三级控制算法;针对Clipped-optimal半主动开关控制算法提出了修订的Clipped-optimal半主动开关控制算法,并对控制效果进行了比较分析,充分验证了修订的半主动控制算法能够有效提升受控结构的控制效果。
Based on the inherent characteristic of MR damper with bidirectional adjusting damping force,utilizing the properties of MR damper with bidirectional adjusting damping force with three states of output powers,a medium bangbang control algorithm and a hierarchical control algorithm of large-span space structures were proposed according to traditional bang-bang control algorithm.A revised clipped-optimal control algorithm of large-span space structures is proposed according to traditional clipped-optimal control algorithm.The control results of different control algorithms were compared and the efficiency of the proposed control algorithms was verified.The control levels were greatly upgraded.
