For　the　vibration　control　of　structures　under　earthquake　and　wind　excitation,　the　active-passive　hybrid　tune　mass　damper　(HMD)　is　presented　and　the　realization　tactic　of　the　control　device　is　proposed,　which　adopts　active　mass　damper　(AMD)　driven　by　linear　motors,　hollow　rubber　bearings　as　restoring　force　springs　of　the　tune　mass　damper(TMD),　and　guide　rails　as　supported　structure.　Then,　the　control　effect　and　damping　mechanism　of　the　HMD　for　the　dynamic　response　of　the　structure　are　analyzed　under　external　excitations.　Meanwhile,　the　influence　of　feedback　response　on　control　effect,　control　force　and　displacement　AMD　are　discussed.　Finally,　the　shaking　table　test　of　the　structure　controlled　by　HMD　is　carried　out　based　on　linear-quadratic-gaussian　(LQG)　and　control　algorithm.　Simulation　and　experimental　results　show　that　HMD　can　effectively　suppress　the　dynamic　response　of　the　structure　and　improve　the　performance　of　TMD.　In　order　to　solve　the　problem　of　AMD　shifting,　the　displacement　of　AMD　should　be　chosen　as　a　control　object　and　feedback　vector　when　the　AMD　driven　by　linear　motors　is　taken　as　the　active　control　device.　The　control　effect　of　the　LQG　control　algorithm　is　better　than　that　of　thecontrol　algorithm,　and　the　feasibility　of　the　HMD＇s　hardware　system　is　experimentally　proven,　which　supports　the　application　of　the　HMD　control　system　to　pure　engineering.　©,　2015,　Nanjing　University　of　Aeronautics　an　Astronautics.　All　right　reserved.
