中文摘要：
研究了基于等价输入干扰方法设计建筑结构抗震控制器,以抑制地震引起的建筑结构震动.该控制器通过推测一个加于控制输入频道的等价震动信号,并直接将其与控制输入进行叠加,以保证震动控制性能.对等价输入干扰结构主动控制器的震动抑制机制进行了分析,表明该控制系统具有二个自由度.通过对一幢受地震冲击的三层建筑进行数值仿真,验证了该方法进行建筑结构抗震的有效性.
英文摘要：
This paper deals with the problem of the active control of building structures during seismic shocks. The controller, which is designed by employing the method of equivalent input disturbance, suppresses earthquake-induced vibrations. The vibration control performance is guaranteed by the control structure, in which an equivalent vibration signal on the control input channel is estimated and directly incorporated into the control input. The mechanism of disturbance rejection in the control system configuration is analyzed., which shows that the control system has two degrees of freedom. Simulation results of an earthquake-excited threestory building demonstrate the validity of the method.
