Keywords:hydrauliccylindersystem,double-nozzlebaffleservovalve,control,testbench. Introduction: Hydrauliccylindersystemsarewidelyusedinindustrialmachines,suchascranes,lathes,presses,andsoon.Thehydrauliccontrolsystemisthekeypartofthehydrauliccylinder,whichprovidesprecisecontrolofthepistonmovementandforce.Inmanyapplications,high-precisioncontrolisrequired,suchasintheaviationindustryorinmedicaldevices.Therefore,itisnecessarytodevelopandimprovethehydrauliccontrolsystemtomeettherequirementsofhighprecisionandefficiency. Double-nozzlebaffleservovalvesareadvancedhydrauliccomponentsthatcanprovidehighprecisionandefficiencyinhydrauliccontrol.Theycanrealizeconstantpressurecontrol,constantflowcontrol,andproportionalcontrol.Therefore,theyarewidelyusedinhydraulics,aviation,marine,andotherindustries.Inthispaper,weproposeahydrauliccylindersystemwithadouble-nozzlebaffleservovalvecontrol,whichcanprovideprecisecontrolofthehydrauliccylinder’spistonmovementandforce.
