Abstract:Thebraking performanceof wheledrobots determines the stabilityof system movementand theaccuracyof path tracking.Inordertoimprovethebrakingperformanceof wheledrobots,anewlowdelayelectro-mechanicalbraking (EMB) actuatorstructureisstudied,andalinearactivedisturbancerejectioncontrol (LADRC)strategybasedonoptimalsliprateis proposed.Thethree-dimensionalstructuredesignofEMBactuatorisoptimizedbymeansofSolidWorkssoftwareacording tothe EMBbrakingprincipleandfunctionalrequirements.According totheoptimalslipratecontrolprincipleof thedriving wheel braking,theelectromechanicalcouplingdynamicsmodeloftheEMBactuatorbrakingprocessisderivedbycombiningwiththe single wheelmodelandtheBurckhardt tiremodel.Undertheconditionof modeluncertaintyandlargedisturbance,thedesignof LADRC brakingcontrolerbasedonsliprate iscompleted.Thesimulationtestingresultsof braking performance in multi-road conditionsshowthattheproposed methodcanreasonablyadjusttheoptimalsliprateofbrakingcontrolof wheeledrobot,and the adhesion coeficient of wheel braking always can reach the peak,which ensures the reliability of braking process.
