摘　　要：针对一类含非匹配不确定项的非线性系统提出一种间接自适应模糊滑模控制设计方法.构造了线性切换面确保滑动运动稳定,用监督控制确保系统状态有界,设计了自适应模糊控制器确保到达条件成立.该方法不仅确保系统稳定,而且抑制了抖振.仿真结果也证明了此方法的有效性.An indirect adaptive fuzzy sliding mode control design method for a class of nonlinear systems with unmatched uncertainties is proposed. In this paper, a linear switching surface is constructed to ensure that the sliding mode motion is stable, a supervisory controller is used to ensure the states are bounded, an apaptive fuzzy controller is constructed to ensure that the reaching condition is satisfied, the proposed method not only can ensure the closed-loop system is stable but also can restrain the chattering efficiently. Simulation results demonstrate the effectiveness of this method.
