摘要 Wind loading on the high-rise buildings is complicated in nature, especially when the across-wind motion caused by the aero-elastic vortex shedding effect is considered. In this paper, a 4 degree-of- freedom scaled (1:300) model of a high-rise building equipped with active mass driver (AMD) is constructed on a wind tunnel to experimentally verify the applicability of active control for wind- induced motion under varied attack angle of wind. A systematic system identification scheme simply based on the input/output relation is proposed for the construction of nominal systems. The control law is determined based on the Linear Quadratic Gaussian (LQG) theorem in which a dynamic output feedback equation with acceleration feedback is formed for practical implementation. The experimental results show that the performance of the active controller following the design process proposed is remarkable in reducing the responses of high-rise buildings under different attack angle of wind. Furthermore, despite that the nominal system contains system uncertainty, the performance of LQG control remains quite promising and robust.
