中文摘要
      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．
英文摘要
      The problem of fuzzy sliding mode control for singular uncertain systems is studied in this paper.The control architecture employs fuzzy systems to compensate the dynamic uncertainty.By means of Lyapunov theorem,all states of the closed-loop system are proven to be bounded. Since the proper fuzzy logic switchings are applied, and the control signal is smoothed,the chattering phenomenon which is inherent to the conventional sliding mode control is depressed.Finally,approxima- tion of practical sliding mode is studied.The effectiveness of the controllers designed in this paper is illustrated by computer sim-ulation.
