ABS自适应PID控制算法的仿真研究

Emulation research to ABS self-adaptive PID control arithmetic

现在汽车上采用的ABS产品都采用逻辑门限值控制方式，以德国BOSCH公司开发的ABS产品为例，详细阐述了这种控制方式的控制过程，然而逻辑门限值控制方式对于不同车型的逻辑门限值的要求有所不同，因此通用性能差。这里介绍了一种自适应的PID控制方式，在模型未知的情况下能很好地调整比例、微分、积分三个参数，将其应用于ABS上，可获得更好的制动效果。

The current ABS products on the automobiles are all using the logic limit value control arithmetic, just take the ABS products from German BOSCH Company as an example, it elaborates the control process of the control way, however, the logic limit value control way needs the different logic limit value concerning the various types of buses and the universal performance is poor. This paper presents the seff-adoptive PID control way, it will adjust the ratio, differential coefficient and integral under the unknown models and applied on the ABS in order to achieve the better brake effect.
