| Abstract: |
| The paper focuses on the decentralized control of vibration of tall buildings under earthquakes and studies the substructure division tactics of tall buildings by introducing information-sharing overlapping decentralized control strategy.Based on optimal weight matrix of Linear Quadratic Regulator Optimal Control(LQR)and optimal output evaluation matrix of H∞ robust control,the paper furthermore analyzes and evaluates the control effect on tall buildings with different substructure divisions.A typical 20-floor seismically excited building is used to analyze the performance of the control strategy.The results indicate that the two overlapping decentralized control tragedies proposed here can guide the substructure division of tall buildings under overlapping decentralized control.The strategies can guarantee a satisfactory control effect and keep the control force within a reasonable range. |
