Abstract

Uncertain nonlinear systems with unknown parameters are considered in this paper. A robust adaptive tracker via state feedback control is designed for tracking given reference signal. The adaptive tracker design is constructive and it is of robustness to the uncertainties of both the unknown parameters and the systematic states. The global stability of the resulted closed-loop system is proved and the epsi-tracking problem has been solved. Two simulation examples are given to show that the tracking effects of the designed robust adaptive tracker are good, and the control quantities used on the spot are within the range of the admissible control as well.
