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。

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.
