摘要：

Servo　valve　is　simplified　as　linearity　in　the　designing　of　electro-hydraulic　servo　system.　It　is　accurated　at　low　flow,　but　the　performance　of　servo　valve　is　different　from　flow　volume　actually.　With　increasing　flow　volume,　the　frequency　at　90°　phase　decreases　dramatically,　it　is　about　60　Hz　when　flow　volume　is　ninety　percent　of　maximum　flow.　In　order　to　satisfy　the　control　performance　of　system,　this　frequency　is　demanded　to　be　twice　the　frequency　of　system　need.　It　is　very　hard　to　meet　the　need　at　high　flow.　First-order　and　second-order　compensation　algorithms　are　adapted　in　this　paper,　and　their　application　is　investigated　in　shaking　table.　The　analysis　results　show　that　performance　of　servo　valve　is　improved　with　both　first-order　and　second-order　compensation,　except　that,　second-order　compensation　is　better　for　the　demand　of　shaking　table　control　system.
