✦ Synopsis
In this paper, two issues in structural control are discussed. First, the prediction-type Kalman ®lter approach is used to estimate the full-state variables of a building's seismic response from a limited number of measurements and the full-state feedback control strategy can be applied. The result is compared with the modal dynamic reduction method and traditional full-state feedback control. Secondly, the time-delay of an actuator is considered in the control strategy. Based on the Pade  approximation, a differential equation for the delay-time of the actuator is developed; then the feedback iteration path of the actuator is included in the control algorithm. Using the example of a 6-story eccentric building with a dual active tuned mass damping system, the above two issues are discussed in relation to a strategy for the control of bending±torsion motion of a building during earthquake excitation.
