controlling building vibration due to a seismic disturbance. The dynamic system is of a realistic four story steel moment resisting frame modeled as a lumped mass system to reduce the degrees of freedom. The feasibility to apply the active control with Kalman-filter is verified from the investigation of the controllability and the observability of the building system.
As results, the responses of the controlled system were compared to those of the uncontrolled system. The effects of attaching the limited number of controllers at different locations were investigated. Also, the responses of the full state feedback control(LQ) and the system with Kalman-filter were compared to evaluate the capability of estimating the unmeasured state variables that the Kalman-filter was supposed to offer.
