Design of robust control law to control the vibration of the 20 story benchmark building in response to earthquakes

摘要

In this paper, a lumped modeling method and a robust control design are proposed for controlling the multiple vibration modes of a 20 story benchmark building. The filtered Linear Quadratic (LQ) optimal control method are adopted to design feedback controllers. Feedback control schemes are shown to be effective against real earthquake data. Both the evaluation criteria and the vibration control effects are verified by simulation results.
