摘　　要：针对传统滑模控制的抖振问题,利用线性化反馈技术,将模糊自适应和滑模控制相结合,设计一种新型的模糊滑模控制器。通过模糊推理和基于Lyapunov函数的稳定性分析,获得模糊控制规则的自适应律,构成自适应模糊滑模控制器,有效解决了传统滑模控制中,需要确定参数摄动和外部干扰上确界不确定性问题,倒立摆上的运行结果表明该方法的有效性。A new fuzzy sliding mode controller,combined with fuzzy adaptive control and sliding mode control,using linear feedback technology,is designed for reducing chattering in traditional sliding mode control systems.Based on fuzzy reasoning and the stability analysis of Lyapunov function,adaptive law of fuzzy control rules,which constitutes the fuzzy sliding mode controller,are derived.The controller provides effective solutions to problems in the traditional sliding mode control,such as the necessity to determine the parameter perturbation and external disturbance upper bound.The simulation results show the effectiveness of the method.
