研究了广义不确定系统的模糊滑模控制问题．控制结构中采用模糊系统来补偿动态不确定性．利用李亚普诺夫理论，证明了闭环系统的所有状态是全局有界的．由于使用了模糊逻辑切换，柔化了控制信号，从而削弱了现有滑模控制存在的高频颤动现象．最后研究了实际滑动模的近似问题．仿真结果表明本文设计的控制器是有效的 The problem of fuzzy sliding mode control for generalized uncertain systems is studied. Fuzzy control system to compensate for dynamic uncertainties. Using Lyapunov theory, it is proved that all the states of a closed-loop system are globally bounded. Due to the use of fuzzy logic switching, soften the control signal, thus weakening the existence of existing sliding mode control dither. Finally, the approximation of the actual sliding mode is studied. Simulation results show that the controller designed in this paper is effective
