Abstract

The essence of AMD controller based on the fixed-base structure to control SSI system is interpreted, firstly. Then the applicability of AMD controller based on fixed-base structure to control SSI system is studied through simulation analysis using LQR algorithm. The results show that the AMD controller designed based on the fixed-base structure can control SSI system effectively when the ratio of the frequencies of the SSI system and the fixed-base structure ωs / ωr is larger than 0.9. However, when ωs/ ωr is smaller than 0.4 this kind controller is not suitable to control SSI system. Finally, the shaking table tests about AMD control SSI system built on three kinds of soil parameters are carried out using four kinds AMD controllers. Tests result that while the soil foundation is stiff enough the controllers work very effectively, while the soil foundation is soft the controllers can't control the response of SSI system even make larger deformation and acceleration of the structure. The test results further validate the conclusion of simulation analysis.
