Compared　with　state　feedback　and　dynamic　output　feedback　controllers,　static　output　feedback　control　methods　are　quite　promising　for　applications　to　the　control　of　civil　engineering　structures.　Based　on　the　simulation　results,　shaking　table　test　of　active　structural　control　was　conducted,　using　the　measured　output　from　a　limited　number　of　sensors　installed　at　strategic　locations　of　the　structure.　The　tested　structure　was　a　five-stories　one-fourth　scaled　building　model,　equipped　with　an　AMD　control　system.　Two　tested　cases　were　given　under　various　earthquake　records　and　the　results　indicate　that　the　performance　of　the　static　output　feedback　controllers　is　very　remarkable.　In　addition,　for　the　same　model　with　parametric　uncertainties,　the　experimental　results　show　that　the　static　output　feedback　controllers　are　much　robuster　against　possible　deviations　from　the　nominal　model　than　the　LQR　controller.　The　study　can　provide　a　necessary　foundation　for　practical　implementations　of　control　systems　to　civil　engineering　structures.
