摘　　要：讨论了一类具有变时滞的非线性系统的自适应模糊滑模控制问题,采用线性矩阵不等式方法构造指数稳定的切换面,并利用自适应模糊逻辑系统逼近带有时滞项和干扰的非线性函数的连续上界函数,使系统状态最终趋于原点.仿真结果表明了文中所提方法的有效性.In this paper, the problem of variable structure adaptive fuzzy control for a class of nonlinear variable tlme-delay systems is investigated. Sliding surface is constructed based on the LMI method, which can guarantee that the sliding motion is exponentially stable. Adaptive fuzzy logic systems are proposed to approximate the bound function of the nonlinear function containing the delayed state and the external disturbance. Simulation result verifies the effect of the proposed approach.
