摘要
提出了一种建筑结构在地震激励作用下的主动控制分析方法.该方法根据当前时间步上的结构状态参数,计算下一时间步上所需施加的控制力,即提前一步计算控制力,因此可解决一般主动控制算法难以解决的迟时问题.算例结果表明,本文方法既能大大减小结构的地震反应,又可消除迟时问题的影响,是一种简单有效的主动控制计算方法.
A new algorithm for active structural control response under seismic loads is presented. The control force needed for the following time step is computed by utilizing the structural state imformation at the current time step, that is, the control force is computed at one time step ahead. Therefore, the proposed control law can solve the time delay problems which can’t be solved in most of the control laws proposed so far. The results of the computation show that the proposed control algorithm can greatly reduce the structural response and eliminate the time delay problems, hence it is very simple and effective.
