摘要/Abstract

摘要： 针对半主动空气悬架系统进行了自调整模糊控制算法的仿真研究。以某空气悬架大客车1/4车辆模型为仿真对象,设计了参数自调整的模糊控制器,并以B级路面为随机输入,以平顺性为评价指标,对模型进行了计算机仿真。结果表明,在引入参数自调整模糊控制方法后,车辆的行驶平顺性得到了改善。此外,当汽车行驶工况变化时,该控制器仍表现出良好的控制效果。

关键词: 空气悬架, 参数自调整模糊控制, 均方根值

Abstract: A parameter self adjusted fuzzy control method was applied to semi active air spring suspension of vehicle. A quarter car model and its parameter self adjusted fuzzy controller were built, and computer simulations were carried out with analogous Grade B road as input and ride comfort as evaluation criterion. The results show that the road comfort is improved by the use of the fuzzy controller and the suspension performs robustly at transient driving conditions.

Key words: air spring suspension, parameter-self-adjusted fuzzy controller, RMS
