Structural Active Control Based on the Concept of Equivalent-Input-Disturbance Considering Actuator Saturation
(0) Efficient design techniques are presented for improving the response of seismic-excited buildings under actuators with fimited capacity. The controller, which is based on the concept of equivalent input disturbance, suppresses earthquake-induced vibrations. The controller produces an estimate of the equivalent vibration on the control input channel, which can be used to directly suppress seismic shocks. The configuration of the control system guarantees effective shock suppression. Information about the actuator saturation is taken into consideration. A three-story building structure under seismic loads is used to validate the effectiveness of the proposed method in reducing the structural vibration. Simulation results show that larger actuators result in better performance guarantees.
