Abstract：Asamulti-input multi-output system，theroboticarmof thepassengercarpowerbatery electricexchangerobothas characteristicsofhighonlinearitytrongdynamicouplingandparameterpertubationdirectlyectingtheperfomanceofjb tracking control.Regardingthelow executionefciencyof electricroboticmanipulator，anew powerreaching lawmanipulator tracking control strategy isproposed to improvethe dynamic performanceandconvergencespedof the manipulator.Anew sliding modereaching law isputforward toaccelerate theconvergence speedandreduce thechatering problemofthesystem， anditsconvergencetimeisgiven.Combinedwiththefast-integralliding modesurface，afinitetimetrackingcontrolerforthe manipulatortrackingcontrolsystemisdesigned.Thefinite-timeconvergencepropertyof theproposedslidingmodecontroleris provedbyusingLyapunovstabilitytheorem.Andtheperformanceof thedesignedcontrollerisverified.Theexperimentalresults showthatthetrackingerorof theproposedpowerreachinglawisreducedfromO.738mmtoO.571mm，andits trackingcontrol performance is increaseed by 22.6% ，which effectively improves control accuracy and convergence speed.
