【摘要】 采用二次稳定的鲁棒镇定控制算法解决地震作用下参数不确定系统的结构振动控制问题。通过对两个安装有不同控制装置的多自由度结构的主动控制仿真分析,证实了这种控制算法不仅能有效减小结构的地震反应,同时对结构参数摄动具有很强的鲁棒性。更多还原

【Abstract】 The application of quadratic stabilization algorithm to civil engineering structures under earthquake excitation was proposed.Two MDOF buildings with various control systems respectively under earth excitation were analyzed using this method.The simulation results show that not only is the presented method effective in reducing the response quantities of the seismic-excited buildings but the method is robust as well.更多还原
