Pipeline　vibration　is　one　of　the　biggest　security　risk　of　hydraulic　system　that　seriously　affected　the　work　efficiency　of　hydraulic　system.　In　this　paper,　a　hydraulic　pipeline　vibration　reduction　scheme　based　on　semi-active　control　was　proposed.　The　system　is　composed　of　single　rod　shear　valve　type　MR　damper,　controller,　driver　and　sensor.　The　controller　outputs　control　signal　through　control　algorithm　according　to　the　vibration　information　of　pipeline　that　collected　by　sensors,　and　then　the　driver　adjust　the　control　current　of　MR　damper　according　to　the　control　signal　of　the　controller.　Finally,　the　damper＇s　damping　force　was　adjusted.　In　order　to　solve　the　problem　of　nonlinear　and　time　delay　in　semi-active　control　system,　an　intelligent　predictive　feedback　control　strategy　that　based　on　the　combination　of　intelligent　control　and　predictive　control　was　proposed.　The　adaptive　ability　of　the　intelligent　control　algorithm　was　used　to　overcome　the　nonlinear　problem　of　the　semi-active　control　system,　and　the　predictive　control　algorithm　was　used　to　compensate　the　time　delay　of　semi-active　control　system.　According　to　the　vibration　information　of　the　hydraulic　pipeline,　the　semi-active　vibration　control　system　using　intelligent　predictive　feedback　control　algorithm　to　control　the　MR　damper　to　consume　the　vibration　energy　of　the　hydraulic　pipeline.　©　by　the　International　Institute　of　Informatics　and　Systemics.
