This study presented a new structure and design method for active structural control (ASC) based on the equivalent-input-disturbance (EID) approach. The method considers an absolute acceleration and relative displacement. In the last few decades, ASC has been studied widely, and some advanced control methods, such as the EID approach, was also applied for ASC. Suppressing absolute acceleration is important to protect properties and people from a large earthquake. However, previous EID control systems only considered the relative displacement but not absolute acceleration. In contrast, this study developed an extended EID control system that suppresses absolute acceleration and displacement simultaneously.
