Application of Robust Control to Wind Exciting High Rise Buildings

The robust control theory is introduced into the structure control, and a procedure for the design of stabilizing controller for a structure with parameter uncertainty and model error is proposed. According to Davenport wind spectra, wind filters for generalized fluctuating wind forces corresponding to various modes of vibration are developed. A practical example is discussed. Simulation results show that the method proposed is able to offer good control to the wind excited vibration for the structure of high rise buildings, and the robustness is expected to be excellent.
