Abstract :
This paper presents a design method of adaptive output feedback controller for nonlinear systems with higher order relative degree and some uncertainties in control input term. The controlled system has a relative degree of one from the virtual filter signals as a control input to the controlled system output by introducing two virtual filters. The actual control input is designed for the virtual filter output signals to be a high gain adaptive output feedback control through backstepping in the filter dynamics. The proposed method is useful in the case where only the output signal is available.
