摘　　要：对一类不确定非线性系统 ,提出了一种基于模糊逻辑的连续滑模变结构设计方法。由于使用模糊逻辑控制 ,平滑了切换信号 ,避免了滑模控制所固有的颤动现象。仿真结果表明 ,文中所提出的控制方法 。A scheme of fuzzy logic based the continuous sliding mode control for a class of nonlinear systems in the presence of uncertainties was developed. Since the proper fuzzy logic control was applied, the chattering phenomenon which is inherent to a sliding mode control was avoided by smoothing the switch signal. Simulation results show that the control system exhibits strong robustness against uncertainties and external disturbances of the system model.
