A study on McNamee wheel AGV motion trajectory control
With the rapid development of modern intelligence and automation,mobile AGVs are beginning to play an important role.This paper is devoted to the study of trajectory tracking control method of McNamee wheel AGV(Automated Guided Vehicle),which adopts adaptive sliding mode control in order to improve the performance of its application in the field of automated logistics and manufacturing.Firstly,the McNamee wheel AGV is mathematically modelled to establish its kinematic and dynamic models while considering external disturbances.Secondly,an adaptive sliding mode trajectory tracking controller is designed on the basis of the dynamics model,which realizes the control of the system state by introducing the sliding mode surface,and then the stability of the control method is analyzed by using Lyapunov theory.Finally,the controller is verified through matlab simulation experiments to improve the trajectory accuracy as well as the effectiveness of the AGV.
