摘要
针对一类非线性不确定系统提出了一种自适应模糊滑模控制方法 ,利用趋近律构造理想控制 ,利用模糊逻辑系统逼近其连续项 ,用自适应律和非线性补偿保证滑模到达条件成立 .该方法综合了自适应模糊控制和滑模控制的优点 ,既保证了闭环系统的稳定性 ,又限制了抖振 ,控制效果良好 。
A stable adaptive fuzzy sliding mode control method for a class of nonlinear uncertain systems is presented. In this paper, a reaching law is used to construct ideal controller, a fuzzy logic system is used to approximate its continuous terms, an adaptive law and a nonlinear compensator is used to guarantee the sliding mode reaching condition. The proposed method efficiently combines the advantages of adaptive fuzzy controller and the sliding mode controller, not only guarantee the stability of the closed loop system, but also make the properties of controller better. Simulation results demonstrate the effectiveness.
