| Abstract: | The research on the design method of the MIMO adaptive control on tall buildings under wind is made in this paper. The unified AHMA model is developed after making the dimension of stochastic excitation and observation noise equal. The equations of the d - step - ahead optimum predictors and control law are derived. The SISO adaptive coned equations of tall buildings under earthquake is derived subsequenily based on MIMO ones. The design details about the unified adapive control on tall buildingr under wind and earthquake and an example are given. |
