Abstract

In this paper a robust control design method of piezoelectric moment controller for a building with uncertain parameters on top of a ship lift structure is established. By taking a real ship lift structure built in China as a background, the effectiveness of this method is examined. The results show that the piezoelectric moment controllers can effectively prevent the whipping effect and reduce the seismic response of the building. Due to the stiffness uncertainty of fastigium at the end of the building, the robust moment controllers give superior performance and stability to the normal active moment controllers.
