摘要：

The trajectory tracking control for a class of wheeled mobile robots (WMRs) with kinematic parameter uncertainty is studied in this paper. Firstly, a new Lyapunov function is proposed, based on which, a new kinematic controller for WMRs without parameter uncertainty is designed to make the tracking error system asymptotically stable. Secondly, the parameter uncertainty of the kinematic model is taken into consideration and an modified adaptive law is designed to deal with the uncertainty. Then, in order to improve the tracking performance, a self-tuning algorithm of the parameters of the controllers is proposed based on neural networks. Finally, numerical examples are given to illustrate the effectiveness of the proposed method.
