中文摘要：
针对一类具有未知死区和控制方向的非线性系统，基于I型模糊系统的逼近能力，提出了一种稳定自适应模糊输出反馈控制方案。该方案将动态面技术和输出反馈控制相结合，避免了过参数化问题，从而无需引入调节函数。通过理论分析证明了闭环控制系统所有信号半全局一致终结有界；且选取适当的设计常数，跟踪误差可收敛到一个小的邻域内。仿真结果表明了该方案的有效性。
英文摘要：
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.
