摘　　要：建立了防抱制动系统的非线性、时变数学模型,实现了滑模变结构控制方法在防抱制动系统中的应用,提出了两种由递推最小二乘算法来计算最佳滑移率的估计方法:一种基于附着系数—滑移率曲线的数学模型,一种基于该曲线的形状。仿真结果表明了基于最佳滑移率的滑模变结构控制方案在车辆防抱制动系统中的可行性和有效性。The non-linear and time-varying mathematical model of the anti-lock braking system (ABS) is established, and the application of sliding mode variable structure controller (SMVSC) in ABS is implemented. Two kinds of estimation algorithms of the optimal slip ratio realized by recursive least squares are proposed: one based on the mathematical model of cohesion coefficient vs. slip ratio curve, the other based on the shape of this curve. The simulation results show the feasibility and validity of SMVSC based on optimal slip ratio.
