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 nonlinear and time-varying mathematical model of anti-lock braking system is established, and the application of sliding mode control method in anti-lock braking system is realized. Two kinds of recursive least square algorithm are proposed to calculate the optimal slip Rate estimation method: A mathematical model based on the adhesion coefficient - slip rate curve, a shape based on the curve. The simulation results show that the sliding mode variable structure control scheme based on the optimal slip ratio is feasible and effective in the anti-lock braking system.
