Robust Adaptive Output-feedback Control Of A Class Of Nonlinear Systems With General Uncertainties

In this paper, a class of nonlinear systems (1) with general uncertainties and unknown parameters is considered, and a robust adaptive output-feedback controller is designed for tracking reference signal. The controller is robust to the uncertainties of both the parameter andthe state of the system, 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 robust adaptive control system, and the used data for determining the control action are in the range of the admissible control.
