Abstract: A stable adaptive fuzzy output-feedback control scheme is developed for a class of nonlinear systems with unknown dead-zone and control directions.The design is based on the approximation capability of the first type fuzzy systems.By combining dynamic surface control technique with output-feedback control,the overparametrization in the output-feedback control design is avoided and need not introduce the tuning function.It is proved that the proposed method is able to guarantee the semi-global uniform ultimate boundedness of all signals in the closed-loop system and a small tracking error by choosing design constants appropriately.Simulation results demonstrate the effectiveness of the approach.
