摘要：

To　deal　with　the　loading　difficulty　of　traditional　shaking　table　substructure　test,　a　substructure　shaking　table　test　method　loading　with　AMD　(active　mass　driver)　device　was　studied　in　the　paper.　A　shear-type　frame　structure　that　may　damage　at　lower　floors　was　chosen　as　a　test　subject.　A　so-called　closed-loop　multi-variable　control　algorithm　was　utilized　to　improve　the　control　performance　of　the　AMD　loading　system.　The　feasibility,　test　performance　and　design　principles　and　methods　were　analyzed　and　discussed　through　theoretical　study,　numerical　simulations　and　a　comparison　with　PID　displacement　control.　Results　show　that　the　proposed　shaking　table　substructure　test　method　can　improve　the　accuracy　of　control　significantly.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
