| Research Abstract |
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.
