摘　　要：针对一类不确定多输入非线性系统提出一种新的自适应模糊滑模控制器 ,该控制器在存在模糊逻辑系统逼近误差的情况下使闭环系统跟踪误差小于预先给定常数 ,消除滑模控制中的抖振 ,缓解因系统维数增高所导致的模糊规则爆炸现象。An adaptive fuzzy sliding-mode controller is presented with three advantages. The controller can drive tracking errors of the closed loop system into pre-specified neighborhood of the origin in the presence of approximation errors of the fuzzy logic systems; the method eliminates the chattering encountered when the sliding-mode control is used alone; and the controller can relieve the blast of fuzzy rules ascribed to the increase of the system dimension. Simulation results show the effectiveness of this scheme.
