Since 1990s, there has been a steady increase in the number of buildings enhanced with active response control systems in Japan. Active response control systems are very effective. However, they use a feedback control law and are not suitable for controlling the seismic response of buildings due to limitations of control force and power. In other words, they are limited in application to the range from small to medium earthquakes.To improve the control performance and efficiency of active response control systems, a new feed-forward control method is presented to make use of predicted earthquake ground motion before its arrival.

自20世纪90年代以来，日本采用主动响应控制系统增强的建筑物数量稳步增加。主动响应控制系统是非常有效的。然而，它们使用反馈控制律，并且由于控制力和功率的限制而不适合于控制建筑物的地震反应。为了提高地震反应主动控制系统的控制性能和效率，提出了一种利用地震波到达前的地震动预测信息的前馈控制方法。
