摘要
A control strategy named Sinusoidal Reference Strategy is developed for adaptive feedforward control of wind-induced vibration of super-tall buildings. In this approach a high-frequency sinusoidal signal is adopted as the reference signal for the strategy. Some shortcomings of the conventional adaptive feedforward control method can be overcome. A MDOF general building aeroelastic model with a square cross-section was tested in a wind tunnel. The testing results show that the present strategy can reduce vibration effectively, and can adapt to wind-induced vibration control of tall buildings with dynamic uncertainties and modeling errors.
