In　the　process　of　electro-hydraulic　servo　seismic　simulation　shaking　table　test,　there　exists　interaction　between　the　specimen　and　the　surface,　which　results　in　the　peak　and　notch　of　the　amplitude-frequency　characteristic　curve　of　the　shaking　table　system　in　the　natural　frequency　of　the　specimen　and　its　vicinity　and　affects　the　output　of　the　shaking　table.　In　order　to　eliminate　the　interaction　effects　on　the　performance　of　the　shaking　table　system,　the　force　feedback　compensation　control　is　introduced　into　the　three-variable　control.　Through　simulation　analysis　of　the　shaking　table　test　system　with　the　single　degree　of　freedom　specimen　and　multiple　degree　of　freedom　specimen　show　that　the　effects　on　the　performance　of　the　shaking　table　system　generated　by　the　interaction　between　the　shaking　table　and　specimen　are　compensated　by　the　force　feedback　compensation　control.　The　effectiveness　of　this　method　on　control　of　the　shaking　table　test　is　validated　by　analyzing　the　error　impact　on　the　control　system.　©　2019,　Nanjing　Univ.　of　Aeronautics　an　Astronautics.　All　right　reserved.
