Trajectory tracking control of a self-balancing robot via adaptive neural networks

摘要

In order to ensure trajectory tracking on a two degrees-of-freedom self-balancing robot (SBR) a control scheme, based on the combination of adaptive neural networks and input–output linearization, is presented in this paper. Both external and internal dynamics are analyzed and proof of uniform ultimate boundedness of the position errors is given. The controller performance is assessed via real-time experiments and compared with respect to other control schemes. Better tracking accuracy and disturbance rejection capability is produced by the introduced controller.
