This paper extends the equivalent-input-disturbance (EID) approach to active structural control with a special focus on suppressing the absolute acceleration and relative displacement of a building simultaneously. An equivalent input disturbance is a signal on the control input channel that has the same effect on the output of a system as disturbances do. Since structural control using conventional EID approach only considers the relative displacement and relative velocities of a building, the absolute acceleration may not be suppressed. However, suppressing the absolute acceleration is important for active structural control to protect the building, properties, and people from a big earthquake. This paper presents an extended EID approach to produce an estimate of an EID that suppresses not only the displacement but also the absolute acceleration. The control performance of these systems is also analyzed from the viewpoint of frequency response. The result shows that the extended EID system has better control performance for the natural period of a building than the conventional EID does.
