摘要
文中建立了压电材料智能力矩控制器对具有不确定参数升船结构顶部厂房地震反应鲁棒控制的设计计算方法,并对中国某升船结构的等效结构体系进行了仿真分析。计算结果表明,智能力矩控制器能有效地减小顶部厂房的鞭梢效应。在考虑顶部厂房因端部山墙引起的侧移刚度不确定性的条件下,智能力矩鲁棒控制器的控制效果和稳定性要优于常规的主动控制器。
In this paper, robust control design method of piezoelectric moment controller for the building with uncertain parameters on top of 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.
