In this paper, a tracking control problem is investigated for a class of uncertain switched lower triangular systems with disturbances. A state-feedback controller is designed by using the adaptive backstepping technique and the universal approximation ability of fuzzy logic systems. The fuzzy logic system is used to approximate the unknown nonlinear functions. It is shown that the designed state-feedback controllers can ensure that all the signals remain bounded and the tracking error converges to a small neighbourhood of the origin. A simulation result is presented to show the effectiveness of the proposed approaches.
