| 摘 要： | 建立了基于磁流变流体（magnetorheological，MR）阻尼器的半主动多步预测控制系统，该系统根据结构当前的状态能够预测未来多步的响应，并在系统内部对时滞进行自动补偿．结合一高层结构，对设置多个MR阻尼器的半主动多步预测控制系统进行了仿真分析，在系统内部考虑了时滞的影响，与理想无时滞情况的对比分析表明，该方法能够对时滞进行有效补偿，保证控制系统的稳定性，同时具有很好的减震控制效果．

| Abstract: | A semi-active multi-step predictive control system with magnetorheological （ MR ） dampers was developed, which can predict the next multi-step responses of structure according to the current state, and has a function of self-compensation for time delay in real application. Numerical simulation of a tall building was presented to investigate the performance of the proposed semi-active predictive control system with multiple MR dampers, and the influence of time delay was considered. Comparison between the proposed syslem and the ideal situation with no time delay indicates that this system can reduce the influence of time delay effectively and guarantee the stability of control system with a better vibration control performance. |
