摘要: 影响轮胎充放气的因素比较复杂,为了简便、准确地对轮胎进行预设定值充放气,提出一种基于模糊与遗传逼近策略的轮胎预设定值充放气控制方法。该方法把整个充放气过程分成两步:首先根据预设定值和当前胎压与预设定值的差,模糊推理出充放气的时间进行预充放;然后依次遗传前面的充放气速率逐步逼近至预设定值。实验结果表明,在不同的充放气条件下利用该方法均能简便、准确地充放气到预设定值,精度可达±0.04bar,适用于各种自动轮胎充放气设备,且简便、高效、实用。

Abstract: The influence factors of tire inflation or deflation are very complicated. In order to make tire to be conveniently and accurately inflated or deflated to the preset pressure value, a tire inflating or deflating control method based on fuzzy and genetic approximation was proposed in this paper. The entire inflating or deflating process was divided into two steps. Firstly the inflating or deflating time was reasoned by fuzzy reasoning according to the preset value and the difference between the current tire pressure and the preset value, and tire was preliminarily inflated or deflated according to this time. Then tire gradually approached the preset value by inheriting last inflating or deflating rate. The experimental results show that tire can be conveniently and accurately inflated or deflated to the preset pressure value in this way under the different condition, accuracy can reach ±0.04bar. It is suitable for various automatic inflators, and it is convenient, highly effective and practical.

Key words: tire pressure, preset value, micro-controller, fuzzy control, genetic approximation
