| 中文摘要 |
| 对于一类具有非线性不确定性及外加干扰的系统，本文提出了一种模糊变结构控制方案，控制中只利用系统输出信号和一些辅助信号．利用李亚普诺夫方法，证明了闭环系统全局BI－BO稳定．仿真表明该控制方案可回避通常滑模控制中不可避免的颤动，且系统具有很强的鲁棒性． |
| 英文摘要 |
| A scheme of fuzzy variable structrue control for a class of uncertain dynamic systems with nonlinear unmodeled dynamics arid external disturbances is presented in this paper. Only the output signal and some auxiliary signals are used in the control scheme. According to Lyapunov method，the closed-loop fuzzy control system is proven to be globally stable. Simulation shows that the chattering phenomenon which is inherent to a sliding mode control is avoided, and the control system exhibits strong robustness. |
