防抱制动系统自寻优控制的仿真研究

Simulation Research on ABS Self-optimizing Control Method

提出了一种基于最佳防抱制动效果中制动力矩和附着系数的变化关系的控制规律,该方法可以使系统自动搜寻到峰值附着系数对应的最佳滑移率点并使ABS保持在该点附近工作。将这一控制策略用于单轮及双轮汽车模型,在不同路面状况下进行的计算机仿真验证了该控制方法在ABS应用中的可行性和有效性。

A control method was proposed based on the relationship between braking torque and adhesion coefficient in the best anti-lock braking effect, This method can make the system search the peak value of the adhesion coefficient automatically and keep ABS work around the peak point. The method has been applied to single-wheel model and double-wheel model, Under different road conditions, the feasibility and reliability of the control method were verified in ABS application by computer simulation.
