For　the　shaking　table　system,　the　90　degrees　phase　shift　frequency　of　the　servo　valve　system　is　close　to　the　oil　column　resonance　frequency,　the　bandwidth　under　the　influence　of　servo　valve　features　was　so　narrow　that　it　cannot　meet　requirements.　Multi-variable　control　is　presented　in　this　paper　by　introducing　the　jerk　feedback　on　the　basis　of　the　three-variable　control.　The　theoretical　derivation　and　the　system　simulation　show　that:　the　jerk　feedback　can　reduce　the　oil　column　resonance　frequency,　and　decrease　the　influence　of　the　system　performance　caused　by　the　servo　valve　characteristics.
