Abstract:

In this paper, a class of nonlinear systems (1) with bounded disturbances and unknown parameters is considered, and a adaptive outputfeedback controller is designed for output tracking. The controller can guarantee the global stability of the closed-loop system, and can solve the ε-tracking problem. The simulations show the good track effect of the adaptive controller.

Key words: Nonlinearsystems, Uncerlaityoutput-feedback, Adaptivecontrol, Robustness, Globalstability, ε-tracking
