摘　　要：对一类非线性系统提出一种新的自适应模糊滑模控制器设计方法。将自适应模糊控制与滑模控制有效地结合在一起 ,先用滑模控制使跟踪误差进入边界层内 ,然后启动自适应模糊控制器。该控制器可消除滑模控制中出现的抖振 ,并可在存在模糊逻辑系统逼近误差情况下使系统跟踪误差小于预先给定的任意常数。A new adaptive fuzzy sliding mode controller(AFSMC) for a class of nonlinear systems is proposed, which is composed of an adaptive fuzzy controller and a sliding mode controller. The sliding mode controller drives the tracking errors into a boundary layer, and then the adaptive fuzzy controller is applied. The proposed controller eliminates the chatter encountered by most sliding mode control schemes and can drive the tracking errors to pre specified neighborhood of the origin in the presence of approximation errors of the fuzzy logic system. Simulation results show the effectiveness of this method.
