| Abstract: |
| A decentralized control scheme can effectively solve the control problem of large scale civil engineering structure vibration under earthquake.In this paper,combining the static output feedback,overlapping decentralized control method,linear matrix inequality and H∞ norm control algorithm,the multi-overlapping decentralized static output feedback H∞ control method has been established.The small perturbation matrix was added to the state matrix in order to overcome the computational difficulties encountered in solving the linear matrix inequality (LMI).The vibration control of a twenty layers Benchmark structure model was analyzed with the numerical method.The results show that the part feedback control,the overlapping static output feedback control and the multiple overlapping static output feedback control is similar to the whole state centralized control.The computational cost and complexity of controller design have been reduced. |
