以制动系统的车辆-地面系统的基本数学模型为基础,介绍了三种汽车防抱控制系统的控制方法:逻辑门限控制方式中存在着理论依据差、稳定性品质差等弱点;最优控制理论方法改善了逻辑门限控制方式的弱点,但其本身也存在着缺点;滑动模态变结构控制系统解决了上述两种控制方法中存在的缺点。汽车防抱控制系统的分析方法有频率域分析法、相平面分析法等。这些方法为正确设计防抱控制系统,提供了依据。 Based on the basic mathematical model of vehicle-ground system of brake system, three kinds of control methods of vehicle anti-lock control system are introduced. The logic threshold control method has some weaknesses such as poor theoretical basis and poor stability quality. Optimal control The theoretical method improves the weakness of the logic threshold control method, but it also has its own shortcomings. The sliding mode variable structure control system solves the shortcomings of the two control methods. Anti-lock control system analysis methods are frequency domain analysis, phase plane analysis method. These methods provide the basis for the correct design of the anti-lock control system.
